Cooperation and punishment

Apparently we need to introduce an element of punishment to get people to cooperate, but this is only good in democratic societies.

In countries like the USA, Switzerland and the UK, freeloaders accepted their punishment and became much more co-operative. But in countries based on more authoritarian and parochial social institutions such as Oman, Saudi Arabia, Greece and Russia, the freeloaders took revenge — retaliating against those who had punished them. - http://www.physorg.com/news124046352.html
