You're making other people rich because you're not taking risks. The people at the top are there because at some point, they quit their job and risked everything they own for some crazy idea. Everyone told them they were stupid and that they should get a "real" job and to stop dreaming, the idea didn't go as expected at first, they persevered without earning and eventually they managed to talk someone into believing in them, or they managed to make enough from their product to start hiring, and that's when you came along.

If you want to be the one that makes the money you've got to be the one that takes all the risks. Normal people don't do this, they work for others where its "safe" and so they get their mortgage, spend their life paying it, and live in apparently ignorant bliss.

Start your own company or try just getting in earlier where there's still more risk involved and you get more reward for it. Otherwise just be aware that your employer is paying for your time, give them that time and nothing more.
