Given the choice between greed with poverty vs greed with wealth, I choose greed with wealth aka capitalism. Like I said, capitalism at least does some good with the greed. Socialism, etc. pretends it can make greed go away, but it obviously can’t.

Sidenote, a vanishingly small portion of people in the US are killed or injured in school shootings. They’re obviously bad, but when comparing societies on the societal scale, they make basically no impact.
