Socialism, or its big brother communism, is even worse. It includes the illusion that the world can be a perfect place if government can just eliminate the bad elements in society, which happen to be anywhere from a quarter to half the population. Maybe more if there’s nothing to stop them. And then the rest live in total fear.
Yes, the illusion. Those at the top running things know its impossible to achieve their stated goals. So they can always stay in power as the elite inner party, living like kings because they deserve it for “ushering in” communism.
