I empathize with everything you've said here more than I can describe in words.
This might be of interest to you, link below, in part in explanation of what you've described... as in, why people "seem more interested in arguing about the problems of our world than actually solving the problems of our world."
It wasn't always this way, things have changed. The podcast I link below sheds some light on the changes of the last decade and how they have effected societies across the globe.
I hope you find it beneficial in some way. Thank you for articulating what so many are feeling.
