Multi-family units and rezoning single family plots is great. Trying to get poor people to live in the back yard like a family pet is a humiliating proposition.
But this is the great debate of our generation, I suppose. Are people capable of making choices or not?
I would have loved to have had this option in college. Glad my landlord saved me from humiliation! (And let us be honest, for every useful idiot who thinks they're helping the poor by constraining their options there are ten homeowners who don't want poor people in their neighbourhood.)
