From an evolutionary standpoint, in order to succeed, why do women seek out men with the highest levels of education and income?

In order to succeed, women seek out men with the highest levels of education and income because these men are most likely to succeed. Men with the highest levels of education and income have a better chance at a successful life (if not already successful) that men without. Since the objective is to succeed, women will choose the most successful men in order to gain their success.
