However, this is one issue that's hard to put solely on the foot of the rich or a broader system. Passing in many avenues, not just by class, is really deciding you want to be there and what the terms of your presence will be. It felt at times like trying to get into a club, if you look like you want in, you don't get in. If you don't want in, they let you in. You have to learn to look like you don't want it.
I think rather than teach young children how to hold spoons, or castigate the rich for yet another divide they were born into, probably we should just teach improv skills, confidence skills and encourage people to engage in open dialogue with others. Some solutions don't require us dismantling a system.
If the next time a rich person gives you an askance look and you immediately ask them to explain themselves, guess what, you just equalized yourself with them socially without having to learn which fork to use first.
