Even though there is neither much altruism nor equality in the world, there is almost universal endorsement of the values of altruism and equality - even, notoriously (and as Nietzsche seemed well aware), by those who are is worst enemies in practice. So Nietzsche's critique is that a culture in the grips of MPS [Morality in the Pejorative Sense], even without acting on MPS, poses the real obstacle to flourishing, because it teaches potential higher types to disvalue what would be most conductive to their creativity and value what is irrelevant or perhaps even hostile to it.
