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.

U.N. employees, including senior leadership, should be selected based on merit and competence while continuing endeavors to achieve gender parity and geographical balance.

I think there are lots of ways to exercise ambition and accomplish things using leadership without going into elected politics. So, categorically, I have no intention of going into elected politics. None.

One of my beliefs about leadership is it's not how many followers you have, but how many people you have with different opinions that you can bring together and try to be a good listener.

When women are starting out in their careers, they tend to be confident and look to aspire to leadership role and really want those positions. But then over time, as they advance, they become less confident and don't think they can attain those roles.
