Yes, it has. The original settlers of Jamestown started out as a collectivist commune. Do you know what happened? About half the people figured out that if they were going to be fed regardless, they could just sit at home drinking beer instead of farming. This resulted in everyone starving and having to rely on the natives to survive. Hence our modern Thanksgiving holiday. So yes, communism has in fact been tried in America and surprise surprise it ended up in people starving to death. Shocker.
