White collar-ers are just going to have to get blue collar jobs until the economy normalizes.
That does not work. Upper skill level white collar workers (mostly engineers and other STEM people on comparable levels) would be the ones able to do that, but they are not that affected. They can move, often globally. Their skills remain rare and hard to find and impossible to train regular people for. Who would need to go blue collar is white collar people at the lower and low end. Think they can do it? A semi-competent paper pusher does not make for a competent carpenter or plumber or electrician or welder. (Some will, but not enough to matter statistically.) So what are they going to do (besides voting for more and more extreme political liars)? The number of house-cleaner jobs is limited and even they need some really skill to be done well.
Also, why do you think the economy will normalize? Have you noticed how many countries and whole economic blocs have given up on the US? The EU is pissed and actively working (and succeeding) at replacing the US as trading and military partner. China thinks the US is a bad joke. Canada refuses to be bullied and more and more does its own thing with other partners. And nobody is going to forget that the US is massively unreliable now. Sure, Trump will be gone (better sooner than later), but the idiots and assholes that voted him in will not be and the current clown-show could get a repeat anytime. And businesses looking to do manufacturing in the US or really invest in trading with the US know that and will stay away.
Maybe in 20 years, things will look up again, but only if basically all US administrations in between do a really good job of mea-culpa and real amends. How likely is that? It is far more likely that this is not a temporary recession, but a permanent decline. And these you recover from in terms of half-centuries or longer or not at all.
