Einstein supported socialism.
Pyschos like Trump support capitalism.
I myself grew up in the USSR. I know well the ideology of socialism, and from today's position I can say that socialism is just a utopia, an unfulfilled dream of idiots. It seems that it was just a dead end development of society. It gradually distorts values and unofficially introduces a double morality. Socialism in the name of the people destroys its people. It is better to simply develop, improve and humanize a society without any ideological superstructures.
You definatly did not live in either socialistic or a communistic regime, the regime you lived in is best described as totalitarism. That is why you have such a negative view on socialism, because what you call socialism isnt socialism at all. In fact Comusinm is possible, to an extent at least, you dont understand it because you refuse to think or just simply brainwashed by powers that rule the modern world.
In fact of the matter. Ideal socialism, with its slogan about the equality of all people, as well as its main principle: from each according to his ability, to each according to his work, looks good only on paper. In practice, no socialist state was able to fully implement it. The human factor constantly worked, namely: egoism, suspicion, vanity, arrogance, dullness of people who were in power and all good undertakings were distorted. For example, Stalin during the years he was in power because he put forward the idea that as socialism developed, resistance of anti-socialist forces would grow, he declared the enemies of the people and destroyed tens of millions of its citizens using the apparatus created by him.
