While IQ is a predictor of socioeconomic status, it's also actually a really good predictor of intelligence and almost everything else that we care about behaviorally, under pretty much every alternative measure that anyone has ever proposed.
A lot of people are very anti-IQ, but frankly they're usually just mediocre humanities mucklers who don't realize or accept that true intelligence requires the ability to do math, even if it's not your specialty or interest (the math geniuses amongst us are almost without exception 95+% in verbal ability).
