The real error with Seattle's homelessness "solution" (as elsewhere) is that is just throws money at a problem, doing little but creating a crooked bureaucratic class. In San Francisco, they recently increased homelessness spending from $250m to $280m ... for (officially) 7500 homeless?! That's $37000 for each person (over 3000/mo)! Sure, I know some overhead has to exist, and SF housing is expensive, but if you're going to throw this money around, AT LEAST SOLVE THE PROBLEM! Cutting a check for 3000/mo to homeless person ain't a great idea I know, but it would behoove more than current mentality.
Instead, there's a huge amount spent, and NOTHING to show for it but a bunch of politicians yammer. Same story in Seattle, 3 years into the "emergency", there's a lot of "charity graft" circulating among well-heeled social workers (or whatever grandiloquency they term themselves by now), but little progress on actualities.
