How could income inequality lead to any such instability? FAUX Noose, et al keep telling us how great everything is, how rich people rock and we owe them so much, etc. etc. I can't possibly see how anyone would revolt against that. After all, there's about 1 chance in 100,000,000,000,000,000,000,000,000,000 that you may either win the lottery or strike it rich and be just like them. And you couldn't possibly blow that chance by doing something stupid like revolting.
