If you look at the Hutterite colonies, they're pretty much communistic within their colonies, but they're certainly cutthroat capitalists when dealing with outsiders.
As always, it's likely not an "either-or" situation, sometimes a mixed approach works, too, rather than running from one extreme to the other.
(Of course, they don't let their colonies become too big and unweildy, either, they'll cleave off a new colony when they get too many people. They tend to control a lot of land, btw.)
