> Tall people earn more money than short people, an average of $789 per inch per year, according to a 2004 paper in the Journal of Applied Psychology.

What an absurdly childish argument. Just because on average tall people earn more, it doesn't follow that every tall person on a flight would be able to afford to pay someone not to put them in an uncomfortable situation.

He's talking about effectively exploiting someone's situation.

Or is that the point? That in a capitalist system, it's a-ok to be an arsehole?
