I live in a town that has offered a novel answer to the riddle of "low value humans".

The homeless. The head-injured. Low income families. Recently released prisoners. The impoverished elderly. My town has arranged itself to serve that population.

Or more specifically, my town receives money from the state for providing these services. It's our #1 industry. All the other towns bring their "problem people" here.

It's probably the most efficient approach (within legality). We've concentrated them all in one place. (It's gotten kind of dangerous and filthy.)

It used to be a nice college town.
