We do make some efforts - e. g. social science finds some practices of social networks are unhealthy, which we can use to correct. Do we improve fast enough? Can we use this new potent tool, AI, to help us out of some of our problems?
Maybe a good catalog - a lot of sciences started with taxonomy - of our problems may help. Good ways to talk to each other - I have some friends from the different side of political spectrum, and we learn to talk. More awareness about how our country, at its about-250 year of existence, actually works, should help.
