So I have been reading around in the comments here and I get the distinct impression that you are trolling, or at least attempting to.
You display a weird mix of ignorance and laziness in not reading up on the basics, while you also often try to dumb down or nitpick an answer given to you.
That isn’t how this works, there are no simple answers. Often there are a dozen answers to the same question, depending on who you ask. As a starting point, you could read up (or listen to an audiobook or something) on Marx and his writings. Virtually all leftist movements and ideologies make reference to or are derived from his.
