Friendship is a cheap place to live because it is mostly made up of welfare recipients. They walk the streets carrying their 6-packs, and can sit at the old Ducky's and smoke a joint. Drugs are prevalent and easy access in the Maple Grove estates trailer park, and violence runs ramped at the local school. Anyone who cares enough about their children has transferred their children to other schools. Basically Friendship is so cheap because no one willingly wants to live there. Also I think Mike confused it with Angelica, then next town over which has the town green surrounded by big old houses.
