Post-cold war nukes decreased a lot, but more could still be destroyed. Nukes have no room on this small planet. When I read about the fall of 1963, I feel blessed no nukes were dropped. Almost no room for error politically.

impact "consumerism" (re-distribution of wealth/nobody "needs" 5 cars or whatever excesses) in such a way that we would have more comfortable "safety nets" in society. Not sure how to tackle that. I guess have faith that gov't will help the truly needy in gloomy or bright days.
