How do I effectively demonstrate that greed is incentivized under capitalism?

[Catmatic Leftist]

I'm trying to convince someone towards communism, and he seems to be on board with most communist ideals, but I can't get him to agree that greed exists because an incentive for it exists. How do I explain to this person that greed is caused by scarcity?

Well this maybe an over simplification, but I don't think that anyone denies that profit is an incentive for greed, and I also don't think that anyone denies that capital accumulation or the begetting of consumption is a motive of capitalists.

Are you trying to argue that greed will not exist under communism?

Why is it important to demonstrate that to your friend?
Why do you yourself believe it?

Greed exists in all humans. It has existed before capitalism and it is not unthinkable that it'll exist afterwards. But among capitalists, greed takes on a character of boundless accumulation of money. The capitalist invests a bag of money and gets 2 bags of money out of their investment. And this process is repeatable ad infinitum.
There's only so many physical objecs you can own until you have no space to store them anymore. And besides, nobody has any use for more books than they can ever read, more cars than they can ever drive, more houses than they can ever live in. But money, being the universal equivalent (as in, you can buy pretty much anything with it) always has some kind of usefulness.

In a communist society, the mode of production has been transformed to one where the means of production are managed democratically, for the good of all instead of for the profit of the few. The way the capitalist accumulates money in capitalism is no longer possible and therefore that form of greed is eliminated.

You're in Chicago, right? Take him to the Board of Trade or the Mercantile Exchange [they've merged, right? I don't know if the trading is all in one place now, or still separate] and have him watch the trading in the grain pits, or the Treasury futures etc.

That should convince him. I know it convinced me, years ago.

Well it isn't in the classic sense of greedy people being misers, people who hoard wealth. In capitalism, misers never do well, as that TLC show may demonstrate. What is incentivized is being a capitalist, which affords one a life without want. However, to be a capitalist, you have to have no moral regard as to the origin of your profits, as the alternative is returning to the bottom and life in poverty, inherently low wealth, or both. I mean capitalists aren't some sort of comical villains, if given the opportunity, they would, while retaining their economic state, give everyone a life without want, they try all the time through all kinds of charities. The only problem is that the capitalist system does not provide this opportunity due to its inherent limitations.
