So much material, so little time (today, for me at least).
A few of his key points that I noticed:
> In the real world you can create wealth as well as taking it from others. A woodworker creates wealth. He makes a chair, and you willingly give him money in return for it. A high-frequency trader does not. He makes a dollar only when someone on the other end of a trade loses a dollar.
Not surprising that he uses this example, it's popular. As a retail trader however, the amount of money I lose to a HFT is basically the HFT's commission for making my trade happen. In the old days I would have paid a broker, today I pay much less to my (electronic) broker and an HFT takes a few cents as well. It may seem to be zero-sum, but they are providing a service (liquidity).
But then again, everyone will defend their own interests, as PG is doing, and as finance people do.
> I've seen this myself: you don't have to grow up rich or even upper middle class to get rich as a startup founder, but few successful founders grew up desperately poor.
This really should be the whole article. PG argues for economic inequality the whole time, but this is the real reason why economic inequality is bad.
Economic inequality reduces social mobility, and reduces the pool of potential entrepreneurs.
Also, PG should realize that what he does is basically what finance people do. He's increasing valuations of certain startups, not creating wealth. It's the same game played in the markets.
