Cities were less squalid in the early 2000s, and somewhere in the decade that followed we decided law enforcement and incarceration were doing more harm than good. So, we elected mayors like De Blasio and Progressive DAs like Alvin Bragg and Chesa Boudin.
It doesn't help that in addition, now 100s of thousands of migrants are being bussed in.
Now parks are no longer usable for citizens and sometimes people living on the street or on public transport threaten us physically, but we're reminded to check our privilege.
There's nothing magical - this was a planned trade-off. The goal of Progressives is to treat homelessness and drug use as a shared societal problem to pay attention to, rather than hide under the rug (in prisons and jails).
