One finds the "vehicularly housed" in virtually every neighborhood, including my own. But the animus that drives anti-homeless laws seems to be greatest in the wealthiest cities, like Palo Alto, which has probably spawned more per-capita fortunes than any city on Earth, and in the more recently gentrified areas like Los Angeles' Venice. These places are ruled by majorities of "liberals" who decry, with increasing fervor, the rapid rise in economic inequality. Nationally, 90% of Democrats (and 45% of Republicans) believe the government should act to reduce the rich-poor gap.
It is easy to be opposed to inequality in the abstract. So why are Los Angeles and Palo Alto spending virtually none of their budgets on efforts to provide housing for the very poor and homeless? When the most obvious evidence of inequality parks on their street, it appears, even liberals would rather just call the police. The word from the car: if you're not going to do anything to help, please don't make things worse.
