The "polynomial curve" historical argument is naive and I would have expected better. Movement toward free markets has been precipitated on political intervention, c.f. the shock doctrine, and conservative moves to increase income inequality (repealing financial regulation, Citizens United) do not occur as a historical inevitability.
I am also weirded out by the "hunter" metaphor. The people fighting income inequality are not predators out to get pg's billions, they are working class people who can't afford healthcare or to send their kids to college.
