“What kind of society isn’t structured on greed? The problem of social organization is how to set up an arrangement under which greed will do the least harm; capitalism is that kind of a system.” ~~Milton Friedman
Greed is a natural human emotion and way of relating to the world. Everybody has greed as a toddler and even after we learn about the ideas of property we still want what that other person has. So long as people are people we will have greed. That’s a constant.
In a non-POM economy, greed is a good thing. Greed makes everything work. Without greed, the non-POM system could fail. A greedy person has a strong desire for more things, particularly luxury items and services. The greedy person wants to gain as much money as possible. The greedy person works hard and tries to work smart. Those are greedy people providing food to the hungry, shelter to the homeless, and clothing to the bare. Those are greedy people down in that mine bringing out the ore at risk of life and limb. Those are greedy people working 80 hour weeks to meet deadlines.
But these greedy people in a non-POM economy are working hard to help other people, to make their lives safer, longer, and more comfortable. Those greedy folks are doing their best to provide the most net-benefit possible because that’s how they satisfy their greed. The only way they can get rich is to do a lot of good for others. And they really want to be rich.
So the greedy person in a non-POM economy is a paragon of virtue, always on the lookout for something to do that will help others.
