Ah so silly.

I assume you mean "socialism" when you talk about communism here of course. And there are a variety of different socialist economic theories, so to put an entire type of alternative to capitalism in one generalized category is quite silly. Even the most criticized of the socialist economic policies (Stalin's) industrialized the nation quite a bit and was economically very viable, granted in that particular case it came with authoritarianism, but it is false to assume that authoritarianism necessarily comes with a socialist government.
There are many examples of worker owned companies (or Participatory firms in some cases even, which is the same thing) performing just as well and even better than capital owned companies. There's an article on JSTOR comparing participatory companies with capitalist ones showing that they both perform about the same (And this is just an example of a socialistic economic system)
As for "the capital you produce" part of your argument, I'm not exactly sure where you're going with this. Every worker produces capital and has no control over most of the profit they make, as the owner is in full control of that. They are paid a wage for their work, but don't control all of their work (or not even most of it). The aim of socialism (and naturally communism) is to allow the worker to actually have a say in what they produce.
This doesn't even make sense.
Care to back up these claims?
