Most people who don't want to work today do so because they don't want to get stuck doing jobs they don't like (and options to get a chance at working on jobs they might like are next to non-existent).
So... most of the time, this is actually their way of 'rebelling' in the present system.
Society would be just fine even if 'most' of the global population were so-called 'free-loaders'.
Look at today's society and most jobs. Most aren't contributing to society in a productive capacity at all - they are utterly useless to Humanity's needs and development at large.
Now I understand what you want to tell me. Yes, I agree with this. Monetary based economy system is indeed make people selfish, and think only for themselves rather than contributing to their society
Everything have their own positive and negative effects, I think.
