i have almost the same situation. i was not born rich, but came from a working-class background and am the first in my family to be academically oriented. being successful in life inevitably leads to those people with a working-class background starting to feel like a burden.
they are always jealous. sorry, but i don't have time to listen to some bullshit about how i can get through life so easily. especially when we live in a country with free education. why are you mad at me because you were bad at school? be mad at yourself. you brought yourself into this difficult situation.
working class people are miserable because the only thing they do is complain about their jobs. the only phrases that goes through my head when i listen to the endless stream of complaints is "then why you are in that job? why you don't get more educated? why you don't start a small business?"
"i can't do anything when i get home!" if the work is too hard for you, you are not suitable. start asking yourself what you really want to do if money and employment were not an obstacle. then, get educated, get graduated, start doing the thing you really want, but as an self-employed person or entrepreneur. the more business oriented you are, the less dependent you are on employers.
i hate the phrase "know your roots" because there is no point in life being with people you've outgrown. you have to move forward in life.
i can't stand people from working-class backgrounds anymore. the older i got, the more i began to understand why social segregation is a thing.
you cannot talk to them about anything significant or profound, because they are not highly educated and are not interested in anything sensible. they complain and never try to find a solution (which would be right in front of their noses, i.e. better education and entrepreneurship). they are jealous, but they won't move even a tiny bit to get in the same position as you.
winners hang out with winners because who can stand losers. it's natural to want to be in the company of someone as capable as you.
