Many of those ways happen to be morally questionable at best, and criminal at worst.

An artistic genius is very likely to lose out financially to an averagely intelligent slum landlord no matter how hard they work. Because the opportunities to make money from artistic genius are heavily skewed towards failure, while for slum landlords they're heavily skewed towards success.

There is no sense in which wealth is a level playing field. If you're not born into wealth - still the number one way to be wealthy - the most obviously rewarded trait isn't intelligence, it's sociopathy.

The successful ultra-rich are notorious for greed, selfishness, and lack of empathy. Go to any social event for the ultra-rich and you'll find a disproportionate number of criminals, narcissists, and other kinds of damaged people.

Those are the qualities that make someone a "success". IQ certainly helps, but if you lack the pathological motivation to exploit others it's not going to get you far on its own.
