Isn't giving everyone $1,000 just like giving nobody $1,000?
It would improve the lives of the homeless dramatically I'm sure. But wouldn't rent/food just inflate at the same time?
If apartment supply remains constant, but now the market of renters increases substantially, prices rise right?
Edit: I like these answers. So if I gave a quick overview, this isn't printing money, its a basic redistribution which gives those with less money much more purchasing power. So prices don't rise because of this.
Things like leases and rent are generally fixed over a period of time. So you aren't getting a sudden increase in cost. You are getting the ability to do things like pay off your credit cards, student loans, and catch up on other payments.
Now you are (hopefully) not in debt and living paycheck to paycheck. Maybe you don't have to work a second job to make interest payments, and you can invest in education or something along those lines.
