While what you says is true, it is but simplistically true.
I mean, heck, it could be simplistically said that history shows that superior peoples always have the power to enslave inferior peoples. Not a truth I would care to push.
It has also been said that a corporation has the soul of the inquisition, and yet is is the best and the brightest that reach the top of the corporate pyramid, just as nature intended.
When America's founding fathes started our country, they hoped to rise above some pretty ugly truths.. Unfortunately they were starting their idealistic quest deep in the hole of slavery, which most of them hoped would soon die away on its own.
But it took 600,000 deaths via ciivil war to end overt slavery, and still a kind of covert slavery marches on.
