It doesn’t help if you can’t afford a house. If you just look at a simple crude statistic like gdp per capital US is 83% higher. You can’t make stuff appear out of thin air, there’s less resources to go around and people are objectively worse off
It actually does help, in fact it helps MORE if you cant afford a house, or are homeless, to have a strong social net.
Not arguing that the US isn't richer or can offer more financial resources to its citizens.
