I don't get why many people think it's sane to make everyone's life worse (by making public transport scarce, expensive, and denying economic growth coming from increased efficiency of a good public transport system) just to avoid someone getting something for free, i.e. homeless getting reasonable accommodation. Bus seat seems like a pretty low bar to clear for a wealthiest country in the world, and yet apparently even the wealthiest state in the wealthiest country can't provide anything better for its residents. How come?
