The answer to this question is a resounding NO!
That is certainly the answer because captalism does not breed greed -- the human condition breeds greed.
In other words, greed stems from all of the character defects that human beings have, not from a particular economic system.
That is true because the "sin of greed" is just as prevalent in such communist societies as Cuba and North Korea as it is in the capitalist societies of the world.
In communist Cuba, for instance, there are a considerable number of people in that country who are amassing what could be described as obsene levels of wealth in the underground economy that exists there.
Also, the very same thing that is presently taking place in communist Cuba took place in the old communist Soviet Union.
All the way from the Bolshevik Revolution in 1917 to when Ronald Reagan urged Mikhail Gorbachev to "tear down that wall," large numbers of Soviet-communist comrades participated in huge underground economies in which many of them demonstrated their greed by making far more money than they would ever be able to spend.
Thus, capitalism is not the monster. The imperfection of human beings is the monster.
