IQ is more important than social class
This is a structural equation model of a cohort of Swedish men. It shows that IQ is an important determinant of income and especially occupational position. Much of its influence is indirect: it is a strong predictor of educational level which, in turn, is a powerful determinant of both income and especially occupational position. Parent's social class, by contrast, is comparatively less important. It has little to no direct influence on income or job position, and predicts educational level only moderately.
A whole academic field--sociology--developed on the view that social class is of critical importance. If disciplines emerged as a result of empirical support, students could major in IQiology.
