I mean aren't you really asking "What should I be doing X years from now"?
If you're looking at your feet you're only going to notice you've walked up to the edge of a cliff moments before you get there. I mean, even with re-education you're taking long term training now in hopes it will work out in the future.
So, pretty much you've said nothing interesting here other than survival of the fittest, which didn't work out great in the past when the unfit were destitute but still alive to cause problems like crime and vagrancy. Is part of your great plan in making things better just unaliving these people?
