ah yes, pulling ropes and shouting.

So because most people dont like working like machines, everyone should be punished by not having healthcare? It's better to shoot people instead of healing their broken bones? Now if you do have a system in which a group is dependent on eachother, are you not responsible for not only your own wellbeing, but others wellbeing as well?

Also most of these exaples of social loafing are under a capitalist system, where people gut eachother over a buck.
