The problem Roosevelt was facing was unemployment. Our problem is inflation and the debt.

Probably not - but at least it might get some useful stuff done.

Bank regulation and directed credit is what you really need.
Even if someone tried pump priming, govt doesn’t actually have control of currency anymore, so any such efforts would be "crowded out" by rampant unrestrained bank (+ interlinked FI) credit creation.

The banks deserve to be in the situation they were in in the '30s, but they aren't due to a generation or two that has let them do what they want and bailing them out after they fail us multiple times. If anything their power has increased. Moronic governments pushing pro-cyclical policies and pumping bubbles is fucking insanity. Well probably just corruption - but democracy seems very weak at controlling it these days.

You could get a lot of rather inexpensive work done if you just put all ICE and DOGE criminals in chain gangs.

We're much more in need of anti-trust enforcement. Productivity is much higher now than at any point in history, but all of the wealth it creates is stolen and hoarded by a very small number of greedy people.

Freeing that up and putting it in the hands of the people would give all of us a high standard of living. Putting a fraction of it into public funding to mitigate the effects of climate change would also support this.

A big reason for the success of WPA was hordes of cheap unskilled or less skilled labor.

But now everything is automated or has higher requirements. You can no longer hire 1,000 random people to build a road, a bridge or a dam, and the results would be far below what skilled people with the right tools can do.

So what types of jobs would this organization do and how well would they be able to match skills with jobs?

That's basically what the 22 infrastructure bill was

No, I believe Americans are America's problem. Just look at what leadership Americans prefer.
