I think something like only turning on the internet and TV for like a single hour each morning and evening would do so much for society, like you wouldn't believe. Not just encouraging better engagement outside of those times, but also causing you to demand better of the hour you do get, avoiding mindless slop.
Have you ever taken a proper break from all media? Like tv, internet, phones, heck even books. You find yourself suddenly with amazing amounts of time. Some people describe being catastrophically bored but for me I just find that all those little tasks that rack up that seem like too much effort suddenly become approachable and you can check off like 6 and still have time for relaxing in some grass and just kinda chatting with passers by. I really think its that simple.
I think the biggest flowering of organizations both small and large happened in the post-WWII period. In the US sure that was a very hopeful time. But many of the other belligerents were reduced to rubble and Germany and Japan were occupied by foreign powers. Yet organizations did still sprout in this period of, what we modern people would probably think as, utter despondency. I think there's more to it than just time and security.
