This is fascinating and a really valuable perspective. Amusingly, it's a case of "causation doesn't imply correlation".
So to draw a further conclusion:
If everyone prioritized wealth equally, then the overall statistics would show higher IQ correlating with more wealth.
Does this actually mean that there's a greater tendency among higher-IQ people to not pursue wealth? E.g. perhaps a larger proportion of middle-IQ people prioritize wealth, while a larger proportion of higher-IQ people prioritize academia or the creative arts or just a healthier work-life balance?
