Being born with a silver spoon up your ass does not make you intelligent.
Im going off of this comment, which I fully agree with.
Being weathy has no baring on intelligence just like being poor doesnt. Some of the smartest people I know arent weathy and some of the dumbest people I know are.
Why would you care about being accepted into a group like that? Why does it matter? You do your job at its best and hang out with people with the PERSONALITIES you click with, with or without the same amount of money.
Like I said, I know poor and weathy alike, I have been friends with both (before I went into therapy and ended up pushing all away) and, to me, I like people that can keep up with conversations, things I have in common with and that just so happened to be intelligent people that where poor as the weathy just couldnt keep up with conversation, seemed to be stuck up (in my opinion), and seemed to think money money money and hide their lack of intelligence behind a bunch of money.
Being in IT allowed me acces to both (though Ive always been poor) and so I can say that though the weathy invited me in, I didnt want to "be in" as I saw them as "dense weathy people" so much so that it took me a while to stop generalizing.
I do know someone today that is well off, not necessarly weathy, and he is the only one that has been able to keep up in conversations and share intrests and is an overall good person that ive come across. The remainder of the weathy are rather hiding behind money in my opinion and I have no idea why you are trying so hard to "fit into" that group. Find another group (money or not) that you can share intrests of and personalities.
