The Creation of Inequality: Myths of Potential and Ability

Hmmm... I think this article is politically motivated and misrepresents the evidence in a number of ways. IQ is a real, accurate measure of ability- it isn't a propaganda tool designed to legitimate inequality. IQ isn't a perfect measure of intelligence, but it is a pretty good approximation. IQ is around 50-80% heritable, which explains the inequality of mental ability and therefore income.

There are problems of 'old boys' clubs' which keep top jobs limited to middle class networks. Highly intelligent kids from middle class families still feel intimidated from applying to the best universities. However, it is important not to let partisan biases affect your views of this topic.
