You could say the same of the aristocracy of Europe over the last few hundred years, but that has effedtively crumbled. There's remnants of "old money" families that were upper-class, but for the most part the merchant class took control of the system that held them down. It took many generations, but the blue blooded dynasties are a dying breed.

Arguably India has the class system tied to the prevailing religion, but religion too has faded with modernity. Systems have a habit of breaking under strain and time.
