People often complain that Thanksgiving is supposed to be about giving thanks for what you have, not gorging on as much food as humanly possible. There is truth to this, but like most of the standard story of the holiday it is unaware of what really happened.
Thanksgiving's real purpose is a celebration of the failure and abandonment of communism, right at the very beginning of what would become America.
Can anyone think of a better way to celebrate the fall of communism than copious quantities of food?
But wait communism had not been propagated yet, it was serfdom and religious persecution that had come to end... oh wait you are 100% correct.
The label "Communism" is much newer than the idea. Much newer. The first pilgrims had operated as communal ownership for the first winter - and it was a struggle. They met, said eff that, and proceeded.
If it documented even in the New Testament. Where one of the Churches held everything in common.
In one of those easy to miss if you aren't specifically paying attention details; later on alms are being sent to that church.
The Pilgrims were utopians who tried to implement it, and failed. That is why they were is such straits.
And they were hardly the only New World colony to try.
