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.

I'm in favor of inequality if it comes about from people making great innovations that make us all better off. And I think those people deserve to be rich. But the people who get rich by lobbying the Congress to give them special protections that come out of the hides of the workers seems to be a bad idea.

Every single time I step into a ring, the same thing is on the line. Take away belts, take away money, take away glamour and fame. Ultimately, I'm fighting for one thing, and that's my life.

It costs a lot of money to make an album in a studio in New York with a producer and musicians. I have to pay a publicist every month. I have to pay for mastering, production, the manufacturing of the discs. Then, to promote an album properly, you have to spend a lot of money.

No one can take away the experience of Yeltsin's freedoms, but Russian democracy will never follow Western models: other authoritarian 'controlled democracies' - Turkey, Taiwan, Mexico - ultimately developed into democracies. But it took decades.

I'm a hard worker, and everything with me is, if I work hard, I should get paid for it. Everything with me, I try to symbolize something flashy like jewelry or a car. The rubbing hands is a symbol of hustling, so it goes back to the money.
