We narrate our stories using abstractions & personifications, mixing symbolic and regular language. What we end up is more poetry than anything. It sounds good when it expresses our feelings. This is (to quote Monty python) no basis for a system of government (or thought).
What/who's intention was it, that you mention above? Are we talking about actual individuals collaborating knowingly to achieve these goals or is this a "nation weeps" sort of abstraction. What, in less poetic terms does "the real goal" really mean?
How does this explain drug policies in Japan or Azerbaijan?
I mean, I definitely agree that Machiavellian dynamics were involved. Electoral feedback loops. Racism. All these played a role.
But.. when someone insists about the "real reason" without demystifying the abstractions... I think we've left the realm or rational discussion. We're in religion territory.
