> to solve global warming we need to make everyone's life worse

This is ignoring that _not_ solving global warming will make everyone's life worse regardless.

It's not ignoring that at all, but I challenge you to go back to the person in China or India that suddenly has amenities and tell him they all have to go away, and everything they worked for over 20 years is gone for "the greater good." You're probably only viewing this from a Western view (already wealthy.)
