Why has none of you entrepreneurial Arkansas dwellers opened a sped living building? Just turn an
old strip motel into ~300sqft apartments and rent them for $450/month. These people voluntarily live in squalor so they'll never complain about the conditions. Even after electric/water you could probably clear $5k/month with 15 units
E: You could buy chips and soda and bullshit in bulk and sell it to the residents for a markup. I guarantee Sammie would spend $4 for a Snickers if she only had to walk to the office instead of the corner store. Must accept food stamps though.
