Uhhh not in the very least. Many of us want to live in areas that have 3-acre minimum lots because of a little thing called nature. Those who want to live crammed into micro-apartments with 1 tree for every 30 people can, but those of us who want a whole town that is more grass that pavement should NOT be accused of classism or racism.
If you really want to help poor people, figure out a system that doesn't box them into ever-decreasing concrete apartments further and further from clean air.
