You seem to have taken Michael Bloomberg as a counter-example to the theory of correlations between height, attractiveness, and earnings potential. It's worth pointing out that Bloomberg is not exactly a 9 to 5 wage drone who labors at the mercy of bosses and their subconscious prejudices -- billionaires as a group tend to be entrepreneurial. Perhaps it's the case that short guys and talented but aesthetically-challenged individuals have even more incentive to drop out of the rat race and take risks that sometimes pay off in big ways.
