Doesn't this imply that on average people just don't care? So, school shooting preventions are just way down in the list of "things I care about", when you have "cushy lives where nobody wants to sacrifice their QOL".
Things aren't binary. Many people care deeply about school shootings. But they don't have the means or power to organize to stop them and, individually, they are powerless.

Decades is a very long timeframe. Countries have achieved more in shorter periods.
What's the last important issue in the US that was democratically resolved?
