People who have lots of children, and people who are prosperous, currently do not care about the future. In fact, it seems the wealthier people are the LESS they care about the future for some reason.

If you ask me, people need to be more educated, and especially when it comes to science and misinformation. Wealth won't make people better people, which isn't to say that inequality isn't a problem, it is, but fixing it won't solve the climate problem. That comes purely from ignorance and selfishness.
