I've always found that people are people, some good, some bad, most somewhere in between. What they wear or the way they speak, or where they live, or where they grew up, or where they went to school, etc have no bearing on that.
Receiving a more privileged education and/or being fortunate enough to grow up with parents who are affluent doesn't make somebody any 'better' than anybody else, it makes them luckier and more likely to succeed financially that's all. My sons have been WAY luckier than I was in terms of the start they had in life and they've had fantastic (and expensive) educations. However I very much hope that they don't share your outlook.
