Homelessness is easy to solve.
A) Universal basic dorms for the poor but otherwise normal adults of sound mind.
B) Mandatory institutionalization for adults with severe mental health issues who are found living on the street.
Crime is easy to reduce.
A) Mandatory long sentences for serious crimes, particularly violent crime.
B) Penalties and prosecution for even small offenses, like shoplifting and graffiti, though not incarceration. Fines, public shaming, long periods of community service, etc.
C) Readjust the welfare system to favor nuclear families with fathers.
D) Decriminalize most drugs, with penalties for public use while driving while using, rather than manufacture & distribution. In essence, you can buy heroin at your local pharmacy, but if you shoot it up in the park, you get a citation and a $500 fine.
Inequality isn’t a huge issue and it’s really not solvable. If you raise the minimum wage to $20/hr and eliminate 99% of Mark Zuckerberg’s wealth, there’s still a crazy amount of inequality between him and the minimum wage worker.
Rather than focus on inequality, focus on three issues:
1) Ensure that there’s a decent minimum beneath which you cannot easily fall (universal basic dorms, employer of last resort jobs).
2) Ensure that men in particular can get a decent living so as to be attractive to women, allowing them to get married and have families. This is a hard one, outside of direct subsidies to men, the only thing I can think of is state owned enterprises that employ men specifically at good salaries.
3) Reduce the power of the oligarchs to set and guide policy. A lot can be done here, though it’s hard to say what would be best.
Unrealistic, of course. But it would be nice if somehow the Overton Window would move in this general direction, instead of the other way.
I would note that the fact that inequality is not solvable makes it the ultimate backstop for the left. If everything else is going well with capitalism, you can always complain about inequality and insist that it’s a crisis for government to solve.
