Greed was meant not only as greed for money but greed for power in general. Money itself is worthless, only its substitution for power is why it's important in the first place.

Under capitalism, profit maximization is necessary for the company you own to survive. You cannot be a "nice capitalist", at least not for long. A person that is nice will have to conform their behavior to maximize profits anyways.

This dynamic does not exist in other systems, where your class membership makes you a relentless recursive tool of the market.
