First to the crime bit… no, Russia has one of the most brutal crime organisations (and yes it also exsisted in the cold war) and the triads in China is the oldest and one of the most powerful in the world, you can’t remove the crimminal mind, humans are compeditive, someone will always prove that all are equal but some are more equal than others.
And when something is illigal, there is a market for the crimminal mind.
To the Communist rule part, i myself like democracy, i like to say what i mean (it is not allowed in any communist country to say what you mean), believe in what ever religion i want (in communism all are equal and “outsiders” are not accepted), earn and spend the money i want and live the life to the fullest.
But i guess you are against these fundamental democratic terms…
Like other utopias communism is a way of thought not of life…
