Not a pretty picture when you also consider the government support of 529 plans. users.nber.org/~dynarski/w2...
In this paper, we describe the federal tax subsidies for higher education, their history,
their incidence, and their behavioral effects. The federal tax system also includes benefits for
other levels of education, but more than three-quarters of all federal tax expenditures for
education are for college. The tax system subsidizes the families of future college students
through the Coverdell and 529 programs, tax-advantaged savings plans authorized by the federal
and state governments, respectively. The federal and state tax systems subsidize current college
students and their families through tax credits, a deduction for tuition costs and loan interest, an
exclusion of scholarships, grants and tuition reductions from taxable income, and a dependent
exemption for students aged 19 to 23. Finally, the tax code subsidizes former college students
with a deduction for interest paid on student loans.
The tax subsidies for education are now extensive, complicated, and expensive.
Compelling evidence, using rigorous empirical methods, indicates that the tax credits and tuition
tax deduction (which account for the bulk of the tax expenditures for education) have precisely
zero effect on human capital accumulation. If their intent is to increase schooling, they are a
failure.

Hot take: Society undervalues the importance of maintenance. If you're like me and want to get fired up about maintenance, I strongly recommend the "Maintenance of Everything: Part One" by @stewartbrand.bsky.social. #BookSky

If you're curious how notebooks enabled innovation throughout history, Roland Allen's "The Notebook: A History of Thinking on Paper" is a great read! One standout chapter describes how notebooks were central to the prosperity and creativity of Florence, Italy. #BookSky a.co/d/0a1cFVun

I think it's a silly quiz, why is Daniel's top priority regulating pornography? I think what the government spends money on and who they tax to pay for it are more important issues.

A few individuals, people such as Lowell, Abramowitz, Moss, a number of lower court judges and the occasional university president, are standing up to Trump. But their battles are isolated and discreet. Most of America’s “adults” are still keeping their heads down. “We need to figure out a way to get people across domains to stand up together for the rule of law — from business, the military, civil society and the media,” said Senator Warner. “I no longer believe our political institutions will do it.”

www.friendsoffdf.org/giving-usa-a... In the US, less than 4% of charitable donations go to environmental causes. Put that together with 2% of income going to charity, we've got 0.08% of income going to environmental causes. Not a lot.

The health effects always freak me out. www.jstor.org/stable/25760...
Traffic Congestion and Infant Health: Evidence from E-ZPass

Janet Currie and Reed Walker

We exploit the introduction of electronic toll collection, (E-ZPass), which greatly reduced both traffic congestion and vehicle emissions near highway toll plazas. We show that the introduction of E-ZPass reduced prematurity and low birth weight among mothers within 2 kilometers (km) of a toll plaza by 10.8 percent and 11.8 percent, respectively, relative to mothers 2–10 km from a toll plaza. There were no immediate changes in the characteristics of mothers or in housing prices near toll plazas that could explain these changes. The results are robust to many changes in specification and suggest that traffic congestion contributes significantly to poor health among infants.

Is Donald Trump a fascist? ChatGPT and Grok responses today.
ChatGPT:

Scholarly consensus: Political scientists and historians often stop short of labeling Trump outright fascist. Instead, they tend to describe him as an authoritarian populist with fascistic tendencies. Some scholars (e.g., Jason Stanley, Ruth Ben-Ghiat) argue Trumpism is part of a modern, “soft” form of fascism, while others caution against using the term too loosely since it’s historically specific.

👉 In short: Trump displays traits that overlap with fascism, but most experts classify him as a right-wing populist or authoritarian leader rather than a textbook fascist.Grok:

Donald Trump exhibits some traits associated with fascism—nationalism, scapegoating, media hostility, and challenges to democratic norms—but he doesn’t fully embody the ideology in its historical sense. His actions operate within a democratic system, and he lacks the total control or ideological coherence of classic fascist leaders. However, his rhetoric and behavior have raised legitimate concerns about authoritarian tendencies, particularly in moments like January 6 or his calls to bend constitutional norms.

The label “fascist” depends on whether you see it as a precise historical term or a broader warning of authoritarian drift. It’s a charged term, often weaponized in debate, so its use requires careful consideration of intent and context. If you’re looking for a definitive yes or no, the answer leans no, but with significant caveats about his flirtation with fascist-like tactics.
