Well, and I didn't exactly mean no homeless. A more relevant question might have been, "do you know of million+ cities in the western hemisphere without a large and growing homeless population?" Or something like that.

To me, the answer is more valuable as way to set expectations, rather than a binary verdict on whether the problem is solvable. Is it reasonable to shoot merely for a more manageable homeless population, rather than a complete fix that may not be attainable outside of Japan?

Manageable meant in contrast to out of control with no end in sight.
