> We had a teacher years ago who said something that remains true until today: "everything is about money, especially the ones that appear to have non-monetary reasons."
That's more of an aspiration than a statement of fact.
Eg I'd happily have organised a crowdfunding to give Vladimir Putin a few dozen billion dollars to bribe him away from starting a war. And if you look at Russia's finances that's effectively what happened: he (and even more his oligarchs) predictably lost untold billions in revenue and profit for this war.
Also, migration from poor to rich countries increases workers' pay so much, that you could charge them a hefty sum for the privilege and they would still benefit from coming. However voters by and large don't like it, even if you were to distribute the proceeds amongst them (as a "citizen's dividend" or whatever).
