Excuse me, how are "liberal attitudes" to blame? We haven't had a liberal/leftist/progressive approach to homelessness in 7 years!
Even then, we never followed thorough on any of the liberal ideas that are so often villianized. We never decriminalized drugs.
We never defunded police. We never implemented housing first (plan yes, actual housing no.) No UBI or social supports that actually provide a livable amount. The tiniest amount of harm reduction but nothing at scale.
Then over the last 7 years we have had program and support cut after cut after cut! Access to welfare has been buried in a litany of paperwork projects to prevent "fraud" and eligibility has been drastically tightened. Basically all supports have been stripped away in favor of a profit oriented "recovery model", how's that actually going?
The current situation is in no way the blame of "liberal social justice warriors" because we haven't actually had any power to implement anything!
I am very sympathetic to the frustration and the vulnerability that folks feel being exposed to "social disorder" but at least place the blame on the side of the spectrum that's actually been in power.
