In January, Paul Krugman had an op-ed called Is Vast Inequality Necessary? I wanted to share this passage from it:

I find it helpful to think in terms of three stylized models of where extreme inequality might come from, with the real economy involving elements from all three.

First, we could have huge inequality because individuals vary hugely in their productivity: Some people are just capable of making a contribution hundreds or thousands of times greater than average. This is the view expressed in a widely quoted recent essay by the venture capitalist Paul Graham, and it’s popular in Silicon Valley — that is, among people who are paid hundreds or thousands of times as much as ordinary workers.

Second, we could have huge inequality based largely on luck. In the classic old movie “The Treasure of the Sierra Madre,” an old prospector explains that gold is worth so much — and those who find it become rich — thanks to the labor of all the people who went looking for gold but didn’t find it. Similarly, we might have an economy in which those who hit the jackpot aren’t necessarily any smarter or harder working than those who don’t, but just happen to be in the right place at the right time.

Third, we could have huge inequality based on power: executives at large corporations who get to set their own compensation, financial wheeler-dealers who get rich on inside information or by collecting undeserved fees from naïve investors.

All three of these are relevant to this project.
