Actually it was a more complex arrangement than you indicate. The earliest methods might have looked communist, but the intent was a journey toward freedom, liberty, and private property. To live in one house because there is only one house isn't exactly a communist intent, but one of necessity. The investors tried to force a communal existence as they believed it yielded a better return, but it was a concept not favored by the "pilgrims". They moved as quickly as possible toward a private property status. Their early failure was for other reasons. To condense it for a political point is to ignore the complexity of the situation. Communism is an economic failure, but the Plymouth Colony isn't the best example.
