Sorry, but you’re highly wrong about your misconceptions of Communism. Communism in no way starves human impulses to succeed or grow any more than Capitalist success does. Communism eliminates the profit motive, yes, but that is historically a highly flawed motive in general.
Socialism/Communism/Anarchism are not fairy-tale Utopias where everyone magically gets a pony, people still work to produce goods and services. However, this production is democratized, in opposition to anti-democratic privatized systems.
