Progressive taxation can offset the effect of growing inequality.

Here's something we're rarely told growing up: our world rewards wealth, not hard work or talent.

For me, growing up as an activist under an oppressive dictatorship in Uganda, the U.N. was a friend to those of us who fought our way to freedom, as it was for the millions who joined decolonization struggles in the African continent.

The world belongs to the wealthy, and nowhere is this injustice more apparent than in the workplace.

I didn't grow up with a lot of money, but I grew up with a lot of opportunities that many people don't have.

It's not easy to be my sons because we're very high profile. We try so hard to give them a normal life. I'm very, very tight with them about money. I don't give that money until they ask, 'I need 100 yuan for my lunch card,' and so on. So they never have extra money.

The degree to which society creates wealth, I think, is largely determined by government and financial systems.

All the money my mom spent on lessons paid off.
