In the communal system it is in the best interest of each agent to work against other agents.

Tragedy of the commons and all that.

[mrguyorama]

That doesn't actually change in a traditional capitalist system. The only difference is that owners and upper classes have more power than the individual to make their interest of getting the whole pot for little work happen

[liaukovv]

In capitalist system owner can enforce cooperation so the pot itself grows. The proportion that workers capture here is of course dependant on external factors, like labour market and laws.
