History has always been written by the victors. We don't hear the history of all the people conquered by the mongols or the history of the people conquered by the Romans or the Egyptians.
What is important is to remember the history of things that go horribly wrong No matter how many times socialism has been tried. It always has and always will fail. With too much power comes greed. Take for example all of our politicians who have been in the senate or Congress for more than 10 years. They are no longer there to serve but feel like they are entitled.
Socialism continues to fail because of greed. And the only place social history programs work is in very miniscule populations That are homogeneous to each other Take for example Norway Finland And other countries that the entire population is similar not extremely diverse.
