It makes absolute sense if what you are concerned with is power and control. Military readiness is relative, not absolute. The power to control politics and the economy is relative, not absolute. The history of ruling classes is a history of those who have jealously guarded their wealth and power and eliminated so far as they could any serious competition.
First, you need some history lessons, because there are tons of occasions where those with power literally funded their competition.
Second, you need to get outside sometimes, because they vast majority of people help those with less power and wealth all the time.
It's only a sick mind that puts someone else down for the satisfaction of being above them, and like, that's not even most racists. Most racists aren't getting out a calculator to make sure they've got more power and respect points than other races.
It is not 'dumb' at all; it is pragmatic.
It is dumb, it's not pragmatic, and most importantly it isn't real. The legacy of racism in America is not something as stupid or on the nose as a bunch of white people thinking "I hope black people never get equality so that I have someone to feel cooler than." That's just the delusion of someone who wants any excuse for a class rebellion, and a race was is good enough for you. But that's just not reality, dude.
They don't need to do better work, just more efficient with respect to pay.
Better work for the same pay is more efficient with respect to pay.
The fact that it actually isn't a grand conspiracy is an even worse indictment of capitalism, frankly.
So you think there's a ruling class deliberately holding people down to exploit them, but also it's not the people it's just the system. Riiiiight.
