1. Trump didn't choose Powell. Someone told him that Powell was the guy.
2. I don't care if Trump chose Powell or not. Powell's successes or failures are his.
3. No, if tariff inflation doesn't show up, Powell will not be a fool. 95% of economists believe that the tariffs will cause inflation. If that is wrong, then it's the economics profession and not any economist to blame.
4. Inflation can manifest itself in many ways. The dollar is already down by 10% since Trump took office. That means we are 10% poorer relative to the rest of the world than we were in January.
5. Remember that economics is a "all things equal" discipline, which is why actual economic measurement and analysis is more difficult than comparing two lines on a spreadsheet. You have to do multivariate regression, at the very least, to examine the effects of different policies.
Right now, there is inflationary pressure from tariffs and disinflationary pressure from the recession that we are either in or will be soon. Remember -- the jobs report last month was sneakily terrible. The job "gains" were illusory or temporary: almost entirely from fewer school teachers moving jobs and increased revenue from the soccer events here. Interest rates are shockingly high and long term they are unlikely to go down no matter what Powell does. It costs money to keep interest rates low, and we don't have much of that any more after the stupid fucking enormously wasteful and mind bogglingly stupid "beautiful" bill.
