Do you want employers to provide housing because you think employers can spend money on housing and food better than employees? Believable.

But I am wary of the efficiency of company towns. In my perspective, things like housing, food, and medicine are "power vacuum" issues, where not taking up these issues is the same as leaving power (and responsibility) on the table for someone else to grab. I also think once power is taken away it's hard to get back.

I view the issues you're talking about as social and government issues, and I'm wary about ceding more and more responsibility to businesses simply because we think government sucks.
