In the long run, wars make us safer and richer

War may be the worst way imanigible to create peaceful societies but it is pretty much the only way.

The Washington Post

I looked at the premise of his book that this article seems to connect with, and it basically boils down to “History shows that societies becomes a lot more peaceful and productive after periods of war.”

Wow, who’d’ve thought that things get better for the people who survive a war? It’s a good thing we can apply survivorship bias to the whole of human history with such confidence like that.

“There’s less death from warfare and economic production diverted to support said warfare when people aren’t fighting wars” is a helluva argument in favor of fighting wars to improve lives and benefit the economy.

It’s like a financial advisor telling you that you should blow all your money in the casino, then quit gambling and start saving.
