After 3 years of growing their food on a communal basis, with some of them choosing not to work to grow food, the colony was failing. Then the leaders allowed those that wanted to work to keep more of what they grew than those that didn't work, and that saved the colony. Prior to that, those people didn't like working hard to give those that didn't want to work the same volume of food that they were given. Once they were allowed to keep more of what they grew, the colony prospered.
To me that makes this holiday as important politically as the 4th of July.
Recently the US has turned from capitalism to State Capitalism, formerly known as national socialism which came out of communism. All of Europe is going broke due to socialism and severely cutting their 'free' services (government spending) while becoming very fiscally conservative trying to survive; and that may not succeed. Personally I don't think it will and I think we are heading for a very deep depression and I don't see anything being done to prevent that. I see things being done to cause that.
ps. I won't be living to 100.
