Businesses could use the money earned through sales pay salaries, make better products, invest in research and development, and a million other things—> they wouldn’t need extra earnings whose sole purpose is kicking money upstairs to the “owners.”

Business could better weather a bad economy because it would be enough to break even; there wouldn’t be the relentless demand from above to make even greater profits.

Ay shucks… Who am I to try to explain this? Just read Understanding capitalism, a great book by Samuel Bowles.
