being white, male, having college-educated parents, and above average aptitude
I don't know which of these is more wrong...
Luck means nothing because it is realistically not permanent in the long run, unless you just hit the jackpot and that lucky day made you affluent.
Being white? I don't even know what that would have to do with anything, unless you grew up in the 1920s-60s, but if you are 30 you were probably job-hunting in the early 2000s, so that doesn't apply to you.
College-educated parents, well, they're better guidance, but at the end of the day you do what you want. I've seen way more unsuccessful brats with both parents as doctors than I have seen successful ones, by far.
Male, well, that does have some truth to it because we are bigger risk takers usually, but nowadays women are showing us up, and you see that at the high-school/college level, and now even in the workforce in many industries.
