These bromides need to be qualified to be of much use. How much reduction? How much money and what kind of housing? What are interesting, meaningful activities that can be prescribed by some central authority in these circumstances? Those are the difficult public policies that need to be worked on.

For example, I'm not so sure that giving folks a small welfare check and putting them in highly subsidized public housing projects is the best solution. I'm sure it does reduce poverty and homelessness with some, but does it also increase unemployment and alcoholism? I don't claim to know the answer, but it's worth exploring. Perhaps a UBI is the answer? Just giving away condoms seems less effective than also creating educational programs. There are plenty of alcoholics with interesting things to do, maybe there is more than just lack of resources at play?
