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.
