You’re being ridiculous. Greed is the “inherent incentive” that leads to regulatory rapture under capitalism and authoritarianism under communism (which one could argue to be the same thing in essence).

The solution is a government of the people, for the people, a.k.a. democracy. Which can choose whichever economic system it damn well pleases, as long as it keeps greed in check through taxation, public services, strong welfare, social discourse, etc. Like social-democratic countries in Europe have been doing for decades. Or try a version of that for communism, I don’t care.
