As Jordan Peterson points out, hierarchies are imbedded into the DNA of not just mammals and chickens, but also in lobsters. So they are not the result of Capitalism. [Presumably lobsters are not adept at being shopkeepers.] So we see Nietzsche was right. Every group is trying to get to the top. Some by intellect. Some by skin color.
The idea of the will to power but modified from Schopenhauer who was trying to say that there is only one dinge an sich. The Will. But Nietzsche asked what does that will want? And he saw what is known as the will to power. You can see much in affairs where you might otherwise wonder what is this or that group trying to get to? Well the answer is blowing in the wind. They all want power. Not equality. Not fair treatment. They want to be on top. But they dress it in fine sounding noble words of equality and justice.
