Economic Inequality: A Simple Rebuttal

Paul Graham argues that "economic inequality per se is not bad." http://paulgraham.com/sim.html

Beyond a certain point this is not true.

In a state of nature, everyone is basically poor because no one cooperates. But this isn't bad for
everyone. If you look like this guy (http://nerdist.com/wp-content/uploads/2015/06/Dwayne-Johnson.jpg)

Chassy is professor emeritus in the department of food science and human nutrition at the University
of Illinois. “As a public-sector scientist, researcher, and academic administrator with more than

professional experience prior to taking up his crusade against biotechnology is as a ballroom-dance
teacher, yogic flying instructor, and political candidate for the Maharishi cult’s natural-law party.”

The HFTer/liquidity provider wants to sit there all day long buying IBM for 99.99 and selling for 100.00
making his penny a share in return for providing liquidity. But the liquidity provider has a problem.
Every now and then Brad Katsuyama (or someone like him) shows up with proprietary information that,
say, IBM should really be trading for 101.00. Brad tries to suck up all those shares being sold for
100.00 as fast as possible before the price moves. That's great for Brad but all of a sudden the
liquidity provider has lost a bunch of money when IBM moves to 101.00 and he can no longer buy for 99.99.

So the liquidity provider tries to recognize as accurately as he can, and as fast as he can, that Brad
