The problem is the high-paying travel jobs have evaporated. The locums market is paying the same crap that full-time local positions pay: $180-250 per hour. The $300+/hr with paid travel gigs are gone.
Oh, and you don't get any retirement match or insurance, no benefits, and have to sleep in a hotel 1/3 the month. I did this last year and the pay was barely worth it, spending 14 days a month in an airport or hotel dealing with COVID in the Midwest was not. Some of these idiot firms don't even offer to pay travel any more, I had one recruiter even list that as a benefit (paying my own travel and deducing it as a business expense).
