fwiw I agree with you on these gripes, tech bros are often selfish, its something I really hate about our industry and I'm struggling a lot trying to find a software job that does good in the world because mine doesn't and it makes me feel awful, but I am trying at least.
And anyone living an unsustainable lifestyle (almost everyone) is selfish though its such a huge problem that putting the blame on any individual feels wrong.
I think where we disagree is that you're so all or nothing with this. People can be selfish in some ways and not others. You can live unsustainably while also having principles in other ways. Things could always be worse. I encourage anyone to care about the world as much as you can without being self destructive about it, and I really try to live that way myself.
> I agree that most (privileged) people behave selfishly
Another great example are the tech bros telling kids to go into the trades. If it was such a great idea, why aren’t they plumbers?
