The unemployment boost isn't going to fix the economy. Unemployment only distorts the economy by competing for labor if we're at full economic output, which we're not. The economy is collapsing at a 33% annualized rate, the fastest in recorded economic history.
You're looking at a crashing economy and suggesting that the real problem is the only brace still propping it up, and suggesting that we knock it out.
Many of these businesses are going to die regardless, because of the failed pandemic response, the failure to enact a sufficient degree of stimulus, and because these businesses are no longer viable with an ongoing pandemic.
And yes, I said plague pit. How in the world do you think it's reasonable for an employee that is not provided with any health insurance (or a bronze plan or whatever) to risk an infection that can stick you with a $1.1m bill, for $7.50 an hour? Employees are, shall we say, not going to respond to that economic incentive, that's not a reasonable trade from any perspective.

Instead, they will stay at home, and 33% of renters are going to miss their payment this month, just as the article says. As they said in 2008: if you don't pay your mortgage this month, you have a problem. If 33% of people don't pay their mortgage this month... the bank has a problem.
The reality is that businesses that require interfacing with the public are going to see a downturn in customers no matter what, and are going to have to start paying for their employees' health care, no matter what. You can't expect people to take on a near-certainty of an extraordinarily expensive hospital stay for $7.50 per hour. People won't do that, and customers aren't coming into the business at the same rate they used to anyway. Those businesses are walking dead and forcing employees to accept sub-market wages to get them back to work won't help that.
