Let me offer a different perspective. Whenever I see your sentiment - that you are choosing to not have kids because the world sucks and you don't see us solving anything - my immediate reaction is that you deserve no voice whatsoever in how the rest of us decide to solve those problems. No voting, no representation, nothing. Having kids, in a sense, is a bet that we'll figure things out one way or another. You've made your bet, and are exiting the conversation because you don't have skin in the game (literally).
That might sound harsh, but it's essentially just the inverse of your sentiment justifying not having kids in the first place because of overwhelming pessimism about the future.
