That's just it, it was not attained it was subsidized and given for a moment. Not that it can't be earned, it just wasn't. Yeah the rich got richer like they always do, but they would have been fine with a great depression as well, look at lebanon and venezuela, it would be much worse in the US.
Worker shortages are no joke, there are $20/h+ jobs that people aren't willing to do. The thing is the rich own the companies and they only do that so they can get richer. If they barely make a profit it isn't worth the hassle. Even six figure jobs are very hard to fill in many industries. Short of making everyone millionaires what is the solution?
It's almost as if a crash and a depression has to happen because of human psychology. When you remember starving then you kill the rich or fall back in line.
Just keep in mind that even in communism the rich party members ran things. Money rules this terrible world and that will not change by any political measure.
