Man you know what’s not hard? Empathy. You know what is hard? Constantly finding ways to make life for others difficult.
Literally just build some free housing that won’t kick people out after extended periods of time, give them social support for jobs, give them mental health support, and feed them.

And blam, you will have a much better city with less crime and a happier population. Oh and it’s cheaper then funding death and destruction
