The looks matter for a competetive hiring situation, where there is two or more candidates with approximately the same education, skills, and experience. So yeah, for your first job after graduation, I can imagine it will be a disadvantage. Then again it also depends on your field: If you graduate with a major in a field with candidate shortage, you will be hired anyway. Simple maths: If there are more vanacies than suitable candidates, all candidates will be hired. So your field will obviously have some impact here. If you go for a typical business/economics degree, you will have much more competition and more candidates than vacancies and I can imagine it puts you at a disadvantage there. If you go for physics, engineering, or biotech, you will be hired anyway.
However, later in life, when you have experience in exactly your field and you're a specialist, the hiring situation is not really competitive anymore. Looks don't matter anymore.
Remember that approx. 50% of all men have visible signs of baldness by 40. How do all those get hired if the other 50% have an advantage in looks? Skill and experience, obviously. If the hypothesis that you cannot get hired if you're bald was true, well, this would a) be measurable, b) would've already been confirmed, and c) result in very funny effects, i.e. significantly more baldies among the young unemployed.
I also went from NW1 to NW3 in 5 years. Still have to deal with that, and that's what life is about. But my Norwood state has in no way affected my hiring situation, but my major is in a field with skill shortage. If you want to get rich, make a degree that is in high demand and short supply, but that isn't exactly news. Then your looks wont matter at all and you will make decent money.
I guess social inequality and equal chances independent of your parents' wealth are really an issue in the US; in most European countries, you get university education until the end of your master's for free (and in many of them the state gives you financial aid while you study). But maybe my definition of rich (a nice 6-figure salary) is also not what the definition of everybody else's "rich" is. With a degree in some STEM field it's not very hard to get a 6-fig salary in your mid-twenties, and at least in my book that qualifies as rich.
@uncomfortable man: The difference is that I put forward arguments. Fred, like he usually does, just said "not my opinion, hence wrong and not worth reading". If he gave arguments it would be different, but I guess he simply isn't capable of doing that for a lack of them.
