It's only money... It comes and it goes. If you're overly attached to it your life is miserable.
War is a tough thing, but there is a duty to protect the innocent. You would hope you can avoid it, but that isn't always possible. Every country will go to war, but it must go for the right reasons, not the kind that makes evil in the world.
I hate to point out the obvious, but it is rather easy to say something like, "There will be another great depression or war.", such things are basically inevitable.
Yes, non-attachment is a good thing and I sure hope yours towards money holds up when you don't have enough to buy food, clothing or shelter. However, I'll wager you'll be somewhere near the front of the bread line to avail yourself of the support offered by the "Marxists" (Democrats you revile in your "43 Alumni for Biden" post) or the good people who create the soup kitchens.
Likewise, yes, war is a tough thing. But the last righteous war to protect the innocent that the United States engaged in was WWII. Every one of them since has been for somebody's financial or political profit.
And what a craven, cynical outlook to claim wars and depressions are inevitable, like God has ordained them or something. Humans make choices to pursue paths of destruction and God doesn't usually intervene. We don't move His bliss needle one bit with our machinations.
