Something to keep in mind:
Unemployment numbers go down as people hit the time limits for benefits and are taken off the rolls.
So just because the number of unemployed people goes down does not mean that there's high employment and everything is hunky-dory.
So you're saying that Ocasio-Cortez is right?
It seems to me she's preaching the wrong message. Obviously, the problem is all those greedy bastards who are working two jobs, thereby depriving millions of unemployed Americans their fair share of the work. We need to make it illegal for anyone to work two jobs. While we're at it, overtime should be outlawed, too. If there's so much work that it can't be done in a standard work day, then companies must be forced to hire more workers.
