The most powerful governments can certainly solve homeless. We have all seen them create a trillion dollars with a keystroke….which goes to the corporations and the billionaire class while the masses get a higher cost of living and $1200 checks.
The government chooses not to solve homeless with the fraction of that number that it would require…200billion. All exploited and miserable classes serve as labor for the rich. The prison industrial complex thrives on an impoverished class of minorities. The police system thrives on controlling the destitute. The tax money that props up these systems is funneled into the pockets of the private corporations that run these prisons, builds their walls, and sells them guns.
