Socialism was invented by Emperor Wu-Ti of China (140-87 BC) by establishing national ownership of natural resources to prevent private individuals from "reserving to their sole use the riches of the mountains and sea in order to gain a fortune and then putting the lower classes into subjection to themselves." - "Our Oriental Heritage" by Will Durant, Simon & Schuster, 1954.
For some obscure reason the old Chinese emperor did not call it by it's correct name, "socialism", either because he was a racist and didn't want to use the English term, or because he was a racist and just didn't know what English term would be used 2000 years in the future.
And, oh, by the way....
...The OP PROVES your statement that Hitler wasn't a socialist to be a total pile of Rodent dropping as big as Rosie O'Donnell.
