Clean drug screens? I'm specifically referring to unemployment, which means people who were working before this happened, and unemployment does not require a drug screen. You are clearly conflating unemployment with other forms of welfare.
Car repairs is a good use of the extra part of unemployment (because it is extra), but I'll bet those friends still paid their regular bills first.
Ideally people would make enough that they wouldn't have to put repairs off. But framing that as a COVID19 issue dooms it to failure. Once the pandemic ends any help ushered in to help with COVID19 will expire. In fact, many existing programs are likely to be gutted after this emergency because the government overspent on it.
So if COVID19 wasn't/isn't the reason, people shouldn't try to use it as the excuse. It dooms them to long term failure, wont solve the underlying problem, and will ultimately make their position worse.
