Really? I have not got that impression so far. I sure don't. I would guess, that it is actually more people are here for tech news and reading like-minded people's thoughts. Keeping up to date with development and technologies.
I guess we can all believe what we want to believe. But Y Combinator (who sponsors this website) is a venture capital firm, which seeks to generate returns on capital by investing in companies. This website, therefore, is designed to reflect and encourage the interests of capital. You can pretend Y Combinator is something other than a venture capital firm if you want, but one day you'll realize that they too only care about getting money.
Be Y combinator as it may, but that not necessarily means, that people frequenting this site are the same.
I think that you have a specific lens with which you view the world, and you're contorting the world to fit that lens.
What would it take to convince you that people don't do everything to attract a high-status mate?
