Can someone explain how this is wrong?

Say I own a factory, and hire workers to run it. I then sit back and take all the profits for myself. How am I not just a parasite?

I understand the factory needs management, but why am I not simply a worker employed as a manager getting a salary. Why do I get to own the profits because I claim “ownership” of this factory?

I also understand investment and risk, but surely, once the investment has been paid back to me with interest, that should be it. Why do I and my descendants get a perpetual claim to the fruits of this factory?

I guess what I’m asking is, what is “property” and “ownership”? Does it just mean I have the ability to call up manpower to kill anyone who tries to take it from me? Is there an actual philosophical justification for this?
