Tale as old as time. Whenever the government simply funnels money out to "businesses" without oversight, it's going to get embezzled. The massive fraud that came along for the ride with PPP COVID relief is just the latest example. The government never seems to learn though, and I'm sure in 2-5 more years, there will be another money firehose and along with it the predictable fraud.
Funny how when it comes to handing money out to low income individuals, the government is willing to spend $100 for every $1 handed out: to scrutinize, means-test, and put these payments under a microscope of enforced rules. But when it comes to handing money out to rich people and businesses, all of a sudden "there's no way we can oversee such a complex program!"
