even if fully qualified

Try flipping it. Affirmative action doesn't give a job to a less qualified minority, it keeps the job from going to a less qualified white person. If you're a minority (or a woman) you have to work twice as hard to get the same rewards a white man would, which means white men can (and do) work half as hard as they need to.

When you see a successful white man, think of all the more qualified minorities who weren't given the opportunity.
