I'm not seeing why a few layabouts would 'ruin everything'. Any more than a small number of welfare-dependent lazyboneses 'ruins everything' today.
I'm not trying to imply that everyone on welfare, even on long-term welfare, is lazy or undeserving of it or what-have-you. I suspect only a very small minority are - lazy people do exist, after all, and where there is a system there will be people who try to exploit that system. The existence of that small minority doesn't even undermine the welfare system, never mind society as a whole, is what I'm saying.
that's probably true. They'd get a decent level of support in terms of welfare anyway, and there'd probably be social ostracism toward those who genuinely refused, out of laziness to contribute in any way. It wouldn't "ruin the system."
