If you believe in the equality of man then I think so. These people didn't individually invent and then produce 1000s of years of collective humam technology and culture and society by themselves to justify such extreme inequality.

And even if you thought so you can't be surprised when the have nots band together and attack or topple the rich society even if it obly for a small temporary gain. Desperation is the largest source of crime and political instability throughout history.
