The ultimate criticism of white privilege as a concept is that when it is implemented into a policy it ends up corrupting groups and individuals identified as "non-white" by advancing and promoting them with less merit than what Reality demands. In short the effects of anti privilege policy is corruption and a social scandal. 

It's also at base an illegitimate concept for a liberal democracy to hold. Which makes one wonder, are we really living in a liberal democracy? In my estimation, not entirely, a patina of social dirigisme and authoritarianism has crept in.
