“led to substance abuse, domestic violence, welfare dependence, poverty and substandard education.”
A lot of this is due to bad personal choices.
In Mexico they faced this with the term here used EJIDOS. They turned the land over to the people, most of them SOLD their properties to investors, went out and got a large TV, a new Suburban, Cowboy Boots, women went to the Beauty Salon, and they wasted, spent it in 2 years. Now they are REAL poor.
Probably a good options was to give them clear title, and let them be treated as any ordinary, regular, citizen of the United States of America... Let them form their own Building Codes and expect everyone in their zone to use a teepee. Works for me.
