This is incredibly clearsighted, in a way that is rare in economic commentary. Contrary to partisan rhetoric, economic discontent is not linked to any one administration. Roughly speaking, folks are upset that two generations ago one job could afford a home and a family. And now it can’t.

Exactly. I don’t even think this is controversial view. Hearst is probably the canonical example of rich barons buying media conglomerates to ensure preferable press. Musk/X or Besos/Post are just the modern equivalents. Musk/X is the first social media endeavor, but makes sense given the times.

Dolly Parton passed. In undergrad, @rbreich.bsky.social would play "9 to 5" at the beginning of lecture when discussing gender inequality. Interestingly, I also remember @janetgornick.bsky.social making a passing comment in lecture that "...at least we still have Dolly" following a sad news day.

The Gulf bases largely serve as support stations for broader operations. There’s reasonable arguments to pull back U.S. investment/involvement, but to maintain the current level of regional stability would require an ally stepping up —which is unlikely.

Your regular reminder that if not for the Trump and Bush tax cuts, federal revenues would keep pace with federal spending indefinitely. Instead, these tax cuts have added at least $10 trillion to the debt. The so called "party of fiscal responsibility" is full of it.

The fundraising texts you delete are working on someone. It’s infuriating and heartbreaking. An 85yo in Ohio gave more than double the value of his home. A 91yo in an Indianapolis senior facility gave 25K times. The DCCC/DSCC don’t just tolerate the spammers who exploit seniors. They take part.

Employers cut jobs in July, and job growth was revised down for May and June. Net result is that the pop in hiring that we saw earlier this year now seems to have largely evaporated. We've now averaged just +20,000 jobs/month over the past three months. #NumbersDay

A 100% tax on all IRA income (capital gains or ordinary income) above $10mm (or some similar amount, indexed to inflation) balance with contributions also capped at that amount is trivially easy to write into law.

To add to this point Professor Logan is making about how media narratives follow elite concern. I’d like to add: indexing forces this inflection point, and what the data shows is that the wealthy have done worse, not that the poor have done better.

I was recently listening to a podcast by @brianbeutler.bsky.social and @mattyglesias.bsky.social, about how healthcare is the defining issue of intra-left division, but when you look at all of the polling data, the connecting thread is that Americans have a very broad demand for material policy.
