Shallow people do, unfortunately, come from all walks of life; intelligence is in no way a guard against it.
By random chance I happen to know a dean of admissions at a research university. He specifically works with Medical Scientist Training Program candidates (otherwise known as MSTP students). These are individuals who are working to get an M.D. and Ph.D. (in a biomedical field) at the same time. They are supposed to be the best and brightest the medical community has to offer. Unfortunately, sexism, racism, and general bigotry is a drastic problem in this group of people. While intelligent, they are so full of themselves that they are inherently incapable of working in a team (and gone are the days when major scientific breakthroughs can be made by lone individuals). Being intelligent in no way justifies assuming that any female labtech or student exists entirely and singularly for your pleasures; yet these individuals not only think that, because the selection criteria excludes such considerations, they are often put into positions where this sort of behavior has free reign.
As I see it, beautiful people may be the most overlooked, the most invisible in our society.
I'd agree with you, but for probably a reason that one wouldn't suspect. That is, I'd generally claim that beauty, contrary to the old saying, is inherant in the beholden rather than the eye of the beholder. All individuals are beautiful and it is only the observers that lack the ability to recognize it. To offer an analogy, I'm fairly tone deaf, so I don't make a claim that I can recognize all beautiful music; but I can still recognize that music I might not see the beauty in could have beauty regardless of my undeveloped senses. In a similar manner, we tend to be form-blind, as it were; I can recognize that there are individuals that I wont be able to see the beauty in but that still have beauty regardless of my undeveloped senses.
So yes, the beautiful people are the most overlooked and invisible members of society, generally because we lack the refined senses to notice that beauty.
But for how you meant it, I'd also agree. However, there is an unfortunately number of beautiful people who have accepted that invisibility whole heartedly. People see them as nothing but a beautiful body, so some of them seem to in turn see themselves as nothing but a beautiful body.
