I think it's extremely unlikely that this team, led by a U.S. Comptroller of the Currency, just messed up something obvious: https://www.lisep.org/team
It's likely the problems are all in the politico framing of it. U7 seems useful. U7 being 24% feels right-ish. That's on Ludwig. Implying that 24% is worse than normal when it's likely one of the best values we've had in decades? That's on Politico.
tl;dr It is very highly correlated to U-3. The paper doesn't include 2024 in the data series but the figure the article cites, 23.7%, is very near all-time best. That's pretty deceptive framing IMO.
