In the real world we have limited resources. Some societies are wealthy enough to sustain a few freeloaders without causing much trouble, but there are limits. If no one does useful work then we all freeze and starve.
It's interesting to look at the social and political divisions that have been growing in Israel over the role of the Haredi (ultra-orthodox). The men are exempt from conscription and mostly don't work for wages. Instead they focus on religious study and survive on welfare and donations. More secular Israelis tend to resent the Haredi as useless lumps who don't do their fair share of work.
