Jesse Dollemore did a good video about this recently that I think explains it better than I can, but I'll do my best: it's good to stimulate the economy, and the relative harm being caused by the government acting to do so in this case is far outweighed by the benefit. Honestly, the thing choking out the economy right now are the people insisting on hoarding their spending power rather than using it, especially when they funnel it out of the country to a tax haven. I'm not talking about wealth, you can't "spend" a theoretical ownership of a company you created, I'm talking about liquid assets, like cash and other forms of money. I highly doubt anyone who fits within the earning restrictions on getting help through the bill is going to save it, at least many of them, and transactions are literally what makes our economy healthy. More money in the hands of people who need to buy things, like food and shelter and such, the better. Every time we give more money to people who have no incentive to actually spend but rather invest in shit that doesn't actually affect the economy positively, we are basically shooting ourselves in the foot. But we'll see, I'm sure it'll get misused and messed up, but hopefully it ends up being a net benefit.
