Where did you get that? As far as I've read, most studies find very poor or no correlations at all between IQ and wealth. And that's striking, given what you'd expect from a metric that measures IQ, isn't it? In fact, those same studies often identify other factors. Interestingly, your parent's class is a hugely important indicator. Sociologists call this phenomenon social reproduction, and it essentially goes against the ideals of the 'american dream', where one can get ahead through hard work. In reality, socioeconomic mobility is quite poor, particularly in the US, which would explain metrics like IQ not being one of the foremost factors in determining wealth. I would agree with you (not on the basis of data but merely by assumption) that IQ today in a mainly services economy is more important than 100 years ago in a mainly manual labor economy.
