Rich white frat boy "tech founders" like being around other rich white frat boys.
You had me at rich.
But seriously...if they got rich by knowing enough tech to found and build a startup, what's your beef with them? And, of course, most people like to hang out, and associate with people that reflect the same traits and beliefs that they do, that's just human nature.
But if YOU are a flexible person, you should be able to get along with most anyone. Me? I went through high school and ran with many crowds. I hung out with the potheads in the parking lot, I knew a lot of the jocks and went to parties with all strata of kids, many of whom had FAR more money than my family did, but that didn't stop me from connecting and making friends of all types.
I found that working early jobs in the service industry helped....bus boy, waiter, bar tender, retail sales all helped me learn even more about how to work with people.
Same skills took me from there to college and later to my professional life. Know what? I still am able to generally speak with and deal with and even schmooze with folks of all types in the world.
Learn some people skills, and don't get so hung up on what other people are like. So what if it is a rich white frat guy.
Learn to deal with them and it might get you in the circles of people that are getting wealthier and help you do the same.
