Maslov is so outdated its laughable. He is responsible for a lot of the common held myths that "everyone is equal" and other bullshit perpetuated by liberalists thinking everyone has equal ability and that there is no difference in race, gender etc...
nietzsche on equality
Behold the tarantula.
Revenge sits in your soul: wherever you bite, black scabs grow; your poison makes the soul whirl with revenge. (99c)
Those who preach equality are such tarantulas. For they are secretly vengeful. But Zarathustra will expose them so to deliver higher men from tarantular revenge. (99d)
But preachers of equality will hold to their ways. They will continue to abuse those who are greater than themselves. (100a)
Such men are enthusiastic in their efforts. But it is not from the fire of their hearts; it is just from revenge. They can be elegant and cold, yet from envy and not spirit. And they may be thinkers, but only out of their jealousy.
Out of every one of their complaints sounds revenge; in their praise there is always a sting, and to be a judge seems bliss to them. (100c)
"For men are not equal: thus speaks justice." Nietzsche
