You know, I think you can interpret Nietzsche's slave morality as the process to master morality. For example, the enlightenment was supposed to free society up from faith-thinking and introduce rational thinking, but (and he right criticizes it) it did not. I think the movement instead brought society out of older slave morality institutions into master morality and which are now considered slave morality again.
I am not Nietzsche expert, but from the little reading I have done it appears that in many context resource poor people have "slave morality" and resource rich people have "master morality". For example, in partner dances, people who are not very popular dance partners argue that "everybody should dance with everybody", whereas people who are very popular dance partners argue that "i did not train 10 years to dance with beginners". And you can see this in almost any human endeavour.

EDIT: it's worth pointing out that Nietzsche also criticizing master morality too.
