And it still hasn’t stopped, 65 pages in
Page 65 of “Owning the Future” by Buller and Lawrence:
“significant swathes of the economy and set to take more.
Unifying ownership and control, the explosive growth of the sector presages a further concentration of economic power. However, contrary to the industry's claims of investing in a productive post-pandemic future, extensive research details the extractive practices favoured by many private equity firms, including loading companies with debt (thereby reducing tax burdens) and asset stripping (such as selling company assets only to lease them back, with the private equity firm rather than the company retaining the cash from the sale).* The corporate form risks being ransacked further through the historic shifts in ownership underway.
On David and Goliath: a Democratising Agenda for the Corporation
We do not, then, live in the world envisioned by the advocates of shareholder primacy, nor in the socialised corporation imagined by Marx or Keynes. Instead, what has come to pass is a deep and ongoing monopolisation of ownership and control rights in the economy, epitomised by the systemic power of the asset management giants, with corporations increasingly reduced to vehicles for extracting income for passive rentier investors. How then can we reimagine the corporation as a vehicle for democratic production, resuscitating the emancipatory potential many have identified in the corporate form?
There is no way that, on the current institutional foun-dations, we can build a world where production is organised democratically to meet society's fundamental needs. Today, property is privileged over the security and dignity of the vast majority, who are subjected to exploitation, coercive…”Page 67 of “Owning the Future” by Buller and Lawrence
“The task ahead is to replace private authority over production with a truly democratic and social institution that organises investment to meet needs based on work undertaken under conditions of substantive freedom within and beyond the firm. That means ensuring the question of the purpose of production is subject to democratic nego-tiation. The corporation is not in any meaningful sense a
'private institution; to the contrary, it's a thoroughly public space, and one of the few that we have been content to maintain as fundamentally undemocratic. Why submit to the prerogatives of the rentier shareholder, managerial elites, and asset management titans, when economic coordination rights within and beyond the corporation could just as easily be organised to serve the many?* Reimagining the corporate form is no small feat, but in fundamental terms, the democratic economy begins where the primacy of property ends.
Reclaiming the Common Wealth: First Principles
The rights enjoyed by owners of capital are not natural, they have been constructed over time through sustained political effort and cemented beneath layers of legal precedent and codes written to construct and protect wealth generating assets.* In contrast to the idea that societal development has travelled along some inevitable path towards the 'end of history', the rights of different classes and peoples have ebbed and flowed, reflecting historically specific distributions of bargaining power within societies.
We need only look to European or Chinese models of corporate ownership to see the range of possibilities, even within the parameters of the present. The dominance of…”

Loved this opening 😄
Article title: “Financing shared ownership” subtitle: “How policymakers can support the financing of shared ownership across the economy”
Contributors: Júlia Martins Rodrigues & Nathan SchneiderOpening paragraph of the article:

A truly democratic society should be capable of extending democracy into the workplace and everyday economic life.
Shared ownership is a fundamental stepping stone toward such economic democracy. In
this context, shared ownership refers to broad-based structures that make company ownership available and reasonably accessible to all members of a stakeholder class-such as its workers, consumers,
neighbors, or other groups of direct participants. This way, the owners of a business are people whose lives its operations affect, not just outside investors seeking profits. Through broad-based shared ownership, access to the responsibilities and rewards of ownership can be distributed throughout society rather than concentrated in the hands of a financial
elite, resulting in more democratic governance and shared prosperity.

I’m a little late on posting this, but some excerpts from @hcrichardson.bsky.social on Apr 24, alongside a snippet from a favorite essay by @mutual-a.bsky.social, with some of my highlights added.
Trump won the presidency by assuring his base that he was a strong leader who could impose his will on the country and the world.
Now he is bleating weakly at Putin.
Trump was the logical outcome of the myth of cowboy individualism embraced by the Republicans since President Ronald Reagan rose to the White House by celebrating it. In that myth, a true American is a man who operates on his own, outside the community.
He needs nothing from the government, works hard to support himself, protects his wife and children, and asserts his will by dominating others. Government is his enemy, according to the myth, because it takes his money to help undeserving freeloaders and because it regulates how he can run his business. A society dominated by a cowboy individual is a strong one.

according to the myth, because it takes his money to help undeserving freeloaders and because it regulates how he can run his business. A society dominated by a cowboy individual is a strong one.
Leaders who pushed this ideology knew it attracted voters. Once they were in power, they could slash government programs and cut taxes and regulations that kept wealth and opportunity accessible to poorer Americans. They argued that a society works best if wealth and power are concentrated among a few elites, who can direct capital more efficiently than government bureaucrats can. Their rhetoric worked: from 1981 to 2021, $50 trillion moved from the bottom 90% of Americans to the top 1%. But those same people talking about individualism to secure votes also knew that the world has never worked this way. In the twenty-first century, U.S. security and the economy depended more than ever on coalitions and government investment.today, Musk and Secretary of the Treasury Scott Bessent got into a yelling match in the West Wing of the White House.
And Musk's vow of $2 trillion in cuts has dwindled down to $150 billion, although that number is not yet verifiable. Elizabeth
Williamson of the New York Times reported today that the cost of firing workers will be more than $135 billion this year, while cuts to the IRS will cost about $8.5 billion in revenue in 2026 alone. And then there is the cost of lawsuits over DOGE's actions.
Rather than working with those government officials already in place to save government money, Musk appears to be trying to display his power over government employees. At the same time, he is scooping up data from various government agencies about individuals in the U.S., a treasure trove that he could use for shaping society, garnering government contracts, or raising money either by selling it or by blackmailing people with it. After today's news that Tesla'sNow I do think that Marx is right about the drive towards simplicity. But it doesn't neatly result in efficiency. Marx's assertion that you can just rationally create productive processes is not just historically questionable (see David Noble on how American manufacturers promoted inefficient automation technologies that enabled more control over workers, for example) but also is theoretically at odds with the aforementioned problems of perfect algorithms.
Certainly, such rigidity can be efficient for particular ends. But it comes at the expense of potentially reconfiguring the process in ways as well as denying tools that would allow for a broader scope of possible ways of working.
But this is kinda the point. Because what the broader capitalist system is optimizing for is control and then efficiency.
States and large, hierarchical firms have a symbiotic relationship with each other wherein both provide something of value that the other cannot when it comes to navigating an uncertain world.
Capitalists naturally pursue technology in a manner that reinforces power because it's how they make workers easier to direct and control which does unlock certain economies of scale and also allows them to drive down wages.
From the perspective of society broadly this is both inefficient and costly in the form of various negative externalities. But from the perspective of the state, this arrangement is preferable because economic centralization enables the state to better achieve its ends precisely because a smaller number of large firms can be more easily mobilized.
And so the state tips the scale in favor of large capitalists in a variety of ways. From the enforcement of property claims acquired through expropriation or conquest, to making forms of self-employment or cooperative enterprises more costly if not outright illegal, to subsidies for transportation infrastructure to name but a few, the state has constantly

A specter is haunting Ethereum-the specter of public goods. All the powers of the old world— maximalists and mercenaries, rent-seekers and reactionaries-have entered into an unholy alliance to exorcise this specter.
Where is the faction that has not been decried as "communist" by its adversaries in the network state? Where is the builder who has not been branded as an enemy of private accumulation, simply for advocating for the commons?
It is time for the stewards of coordination to openly publish their aims, to stand before the networked world and declare: public goods are not theft, they are the substrate of civilization.

They don't see this as dropping the ball. The mental model underlying the design philosophy seems to be very laissez-faire, to the point of techno-libertarianism.

the section i attempted to summarize, in full for anyone curious
A unifying perspective
The book is thus motivated by a concern with economic forces on the one hand and with politics on the other. In clarifying the manner in which it seeks to blend the two, it is useful to dwell on one of the canonical texts in contemporary social science: the Coase Theorem. 23
Coase bases his argument on an example in which a railway runs through a valley populated by farmers. The allocational issue is the number of trains that should operate each day. Transportation is valuable and operating trains produces profits for the railway; but transportation is also costly, for soot and sparks from the passing trains damage the crops of farmers. Acting purely out of a regard for corporate profits, therailway is likely to run too many trains. The costs inflicted upon the farmers by the last several trains may exceed the profits earned by the railway, and society could be made better off by running fewer trains.
Coase argues that a system of property rights could yield the socially efficient outcome: the number of trains that maximizes the sum of the returns to the railway and to the farmers. He also demonstrates that from the point of view of economic efficiency, the precise form of property rights is irrelevant. Equally important, he stresses that this conclusion holds only if there are no transaction costs. It is this last argument that renders Coase's article a contribution to the political economy. For in a world of positive transaction costs, institutions matter. They determine what bargains can be made, what agreements enforced, and therefore what outcomes are attainable through voluntary exchange. They also determine who pays, and who receives payment, when resources are …Politics also matter in Coase's argument because they influence the distribution of economic benefits. Under the system of corporate rights, efficiency requires a flow of payments from the multitude of farmers to the owners of the railway. Historically, the ownership of railways has been tightly held, and the result of this system would therefore be the creation of a wealthy minority. Under the system of farmers' rights, efficiency requires the flow of payments from the railway to the farmer.
As assumed in Coase's argument and as commonly seen in the developing areas, farming tends to be a broad-based industry, with a multitude of small-scale practitioners. This system of property rights is therefore likely to yield a more egalitarian income distribution. The distribution of income is therefore significantly shaped by whether it is the railways or the farmers who dominate the political system and who thereby achieve the power legally to privilege their interests.The two systems of property rights may thus both produce efficient outcomes. But they will yield different distributions of income, and ones that would result in major differences in the structure of demand, the composition of industries, and the kinds of jobs and skills that are socially rewarded.? While equivalent in terms of the degrees of economic effi-ciency, the two institutional bases thus yield radically different developmental outcomes. Which group organizes politically and thereby seizes the power to define the system of property rights thus matters.
This book seeks to bring to the study of development insights generated by the work of Coase, Williamson, Alchian, Demsetz, Klein, Crawford, and others who have explored the significance of institutions. * It explores their political as well as economic features. It thereby attempts to create a way of integrating the political with the economic in the study of development.
