I think inequality has gone past the point where it's helping us all get rich, and it's really becoming a serious threat.

The key is to somehow find a way of tackling rent-seeking, crony capitalism, and corruption - legal and illegal - and build fairer, more equal society without compromising innovation or entrepreneurship.

If someone thinks of something, some new innovation that benefits us all, and the market works properly, they get richly rewarded for that, and that's just terrific, and that creates inequality.

As recognized since ancient times, the coexistence of very rich and very poor leads to two possibilities, neither a happy one. The rich can rule alone, disenfranchising or even enslaving the poor, or the poor can rise up and confiscate the wealth of the rich.
