The fact of the matter is that the poorest in the US have been neglected for decades. If people are not going back to work with new unemployment benefits that simply states that the wages offered by the market are not competitive. Why would I work full-time when I could make more money simply staying at home on unemployment? Your employer must not really value your time if they are offering less than unemployment benefits provide!
I think that is the gist of the problem with the unemployment handouts. But the U.S.is primarily a service based economy. As long as the lockdown is in place, a large segment of the population can't go to work.
