The problems you cited are merely symptoms of structural societal problems. Treating the symptoms is pretty much the only approach we’ve tried because trying to address the systemic problems is woke communist tyranny. The US, for example, has the 5th (and also 6th if you include Guam) highest incarceration rate in the world, and also owns 10% of the top 50 cities for homicides. Making it illegal to be addicted to drugs or too poor or mentally ill to provide yourself with housing does not cure the addicts of addiction, the mentally ill of mental illness, or the poor of their poverty. There’s a reason we eliminated debtors prisons.

Any problem can have a simple solution if you ignore enough about it. If this was entirely about personal responsibility or entirely about providing government services we’d have had these problems licked decades ago.
