It only took a few generations, but we've gone from America, land of the free and home of the brave, to America: we tried it once in the past and there were problems, so we should give up now and never try again.
Public housing can be amazing, especially when the people involved actually want it to succeed.
Besides - even if there weren't many success stories to draw from, which there are - things can be improved on. Just because the first bicycles kinda sucked, doesn't mean that modern e-bikes aren't amazing. There are similar examples everywhere.
What's going on right now is a horror show. It's stupid, economically and morally.
It's a pipe dream to expect public housing to meet the demand for shelter in a political climate like that of the USA. That said, I'll still take as much public housing as I can get in my city.
