First, I’m not a professional economic policy person so I assume they will have much better ideas.
But we could have put rules in place that were enforced retroactively. Something like “you get $600 if you lost your job. Everyone who asks gets it. But when you file your taxes if you didn’t lose your job and you took the money, you have to pay it back.” Stuff like that.
I worked for a consulting company that had a pretty smart expense approval process. They approved everything and audited you severely when you went up for partner. It wasn’t perfect, but it was pretty close as people were really nervous and conservative even though they wouldn’t be audited until years later.
There was also a lot of stuff where unemployment paid more than working so there were perverse incentives to not work and make more money. I had a family member who normally made about$2k/month. He got $600/week in unemployment so took a long time to go back while making an extra $500 per month. Stupidly, he bought a car with the extra money (but he’s been able to keep making the payments).
Just having some cap that paid 80% of your salary in unemployment would have been super simple to implement.
Or some programs ran for over a year. So the emergency stuff could have phased out after 3 months or 6 months.
There’s lots of ways they could have designed interventions much better.
