If you have everything you want, you want for nothing. That is another way of saying you are rich. Seems obvious enough.

"An insatiable drive for wealth is hardwired into our brains by evolution" - I think that is probably nonsense. Taking more than what other people see as your fair share is not a good survival technique in a hunter gatherer economy. Eating up the seed corn is not a good survival technique in a society that's moved on to farming.

And I am pretty sure that "an insatiable drive for wealth" is likely to be anything but a good survival technique for modern humanity.
