You can also take a fairly selfish view and come to the same conclusion. Like, I don't want to see homeless encampments, or really sick and untreated people, or panhandlers, or (...) while I'm walking around in my city. I can solve this problem by 1) moving to a nice suburb, or 2) having my tax dollars go to fix a problem that affects me. 1) is off the table because I want to live in the city, and 2)
while it helps the greater good
also helps me directly. (2 can also be addressed in a draconian fashion, which is not what I'm advocating at all.)
I think one problem is looking at things as zero sum. It's not. If you are healthy and housed and fed then you're not
to be very crass
an eyesore, you're adding to the fabric of the city. I want street musicians who are playing for fun, not because they're trying to make enough to afford dinner.
One of the coolest parts of The Expanse IMHO was that The Mormons commissioned a giant space ship, and it didn't feel forced or far-fetched.
