That newscientist article is a bit old (from 2007) but seems to support sz4kerto's claim that income is correlated with IQ.

“Each point increase in IQ test scores is associated with $202 to $616 more income per year,”

That study claims that the income increase associated with higher IQ doesn't necessarily translate into increased average wealth though as other life style factors may offset the increased average income.
