Are you sure? I’m equally skeptical of the claim that zero sacrifices are necessary in order to grow. The history of every society would seem to disagree.
The question seems to be what’s an acceptable threshold, why, and who. These aren’t easy questions. They’ve been with us since humans first started forming tribes.
(I said much the same thing as you in an adjacent comment, but it’s worth framing the sentiment in a way that’s not mistaken. Otherwise it’s little more than dogma, whether on one side or the other.)
