No, it is not correct, and the data cited in the article do not come remotely close to supporting the conclusion asserted. To be specific, the author has truncated his scatter plot at such a low value ($230,000 net worth) that he has in fact excluded every single individual who would be considered "rich" (his term) from the sample. In brief, the author is disingenuous (to be polite), an incompetent, or both, most likely both.

Incidentally the comments made by others here to the effect that there are other factors besides IQ that contribute to success (i.e. being "rich") are of course correct, but not really relevant to the question at hand, which is whether or not IQ is positively correlated with being rich, which of course it is. High IQ alone obviously does not suffice, but for someone who has the other factors - drive, focus, etc. - high intelligence, as reflected by IQ, definitely helps.

I know some people who keep up on the scientific literature pertaining to psychometrics, statistical correlations between IQ and other factors; if you are really interested, I could put you in touch with them.
