Who makes the rules in your Utopian fantasy world? Every single human-being that is a part of the society upon reaching the age of 18? 17? 16? Who makes the laws in your Utopian world? Adolph Hitler? Jozef Stalin or is it Mao Zedong?
You're pretty comical in a massively uninformed sort of way. People often confuse Communism with Socialism, you're certainly not alone in that presumption.
I've read Marx, and AFAIK, his major work was titled,
The Communist manifesto, not, "The Socialist Manifesto".
True Socialism leans further toward universal healthcare than storm troopers in jackboots.
Russia, and by extension the USSR, never had a true socialist state, it was communist. In fact Russia was leaning toward western views and practices, until Vladimir Putin suffered a massive illness often referred to as, "paranoid delusions of grandeur".
