There has to actually be workers to build houses for the homeless. Or else that will just drive up building cost. Elons fantasy robots aint building houses yet.
The homeless in tent cities ain't on welfare. The majority are disabled, have pets, hoard, drink, smoke do drugs. All of these issues make housing or working for welfare impossible. They need housing vouchers, welfare & counceling.
US debt ain't from taking care of the poor, it's from wars, subsidizing wallstreet, tax loopholes, low taxes on wealthy & corporations who lobby government, corporate greed, corruption.
Look how 95% of Trumps Covid debt went straight to the top & caused massive inflation. Only 5% went to the poor, working poor & lower class who suffer from this inflation.
