At times, it has been used as an excuse to take what "more primitive" people have, to ignore wisdom gleaned empirically because those who gleaned it are 'inferior', to establish "elites".
It also gives those same elites all the excuse they need to keep fixing things that aren't broke.
Marxism, and the Hegelian garden in which it grew, asserts “evolution” or change as a progression toward perfection.
However, Darwin and Huxley did not regard evolution as a progression. Specifically, what appears to be “evolution” is in fact just a result of natural selection, e.g.., we don’t see cheetah that are slow-moving because such animals don’t survive long enough to produce offspring. The biological nice that cheetah occupy requires a fast-moving animal.
Hume said that humans often see progression when there is only sequence. His analogy was that we are like a man who is watching a cat walk past a slit on the other side of a fence. He sees the head, then the body, then the tail, and concludes that the head caused the tail.
