You're getting quite the grilling here OP, however I can see what you're trying to say, I think your post possibly wasn't worded quite right.
Or perhaps people will think I'm also a completely smug asshole too, who knows!
I have friends from all walks of life, genuinely. Sometimes when people who are wealthy say this, it reads as "aren't I so nice! Befriending the poor!" When really they are trying to put across that they are able to connect and hold meaningful relationships with diverse friendship group. No different to religious or cultural differences.
I cam from nothing, had nothing, no helping hands etc. We live in a nice but diverse area. We've grafted very hard and although not rich by any stretch, we are very comfortable and significantly more well off than 70% of the village let's say.
Friendships I made when we first moved here and had nothing, have since dumped me / turned on me (thinking we were friends and later found they were unkind about me to others etc) as our business's grew. They'd tell me " you should be so proud of what you've achieved and have" to my face, then literally bitch about it to others.
It was so painful and I've learn now that some people just find it very hard to watch others do better. That it's about how they feel about themselves and not alot to do with you (unless you really are an unsufferable smug idiot) and they let jealousy get in the way. This baffles me. I think it's fine to think "I wish I had that TOO" but I'd never not want that person to have what they have either, you know? Especially when theyve watched the hardship it took to get to where we are. Sometimes I feel out of place with some very rich friends, but that's okay, they're just living their lives as I am mine, and there will always be differences of normality and perspective there.
I'm not sure what the answer is but I've had to learn not to take it to heart. I just felt like an idiot for not realising the friendship was fake their end sooner!
Sadly I think you're right, it's easier to stick with those who have a life more aligned with your own, less complicated, especially in this climate our tory government have built- very divide and conquer. So much misdirected frustrated and anger to others.
