Fiscal policy should balance growth, equity, and sustainability concerns, including protecting society's most vulnerable.

Having a proper understanding of countries' external positions - current accounts, stock positions, and currencies - is critical to highlight policymakers' shared responsibility to tackle external imbalances before they become too risky.

In reality, while currency movements can have a significant impact on inflation in other countries, dollar movements have rarely had a meaningful or durable impact on prices in the U.S.

With all the globalisation that has taken place, countries are a lot more interdependent and therefore 'coupled.'

I always try to be smart. I try to treat all the money I'm making like it's the last time I'm going to make it.

Under President Obama, we have spent more money - he has spent more money than any other president in this history, actually, the combined total from Washington up to George W. Bush. President Obama has racked up more spending, $1 trillion deficits. And it's time that he join us in this effort to get our fiscal house in order.

Meeting people who want to start a charity, help out their families, or raise money for a good cause has been really fun.

The unending chase for money, I believe, threatens to steal our democracy itself. I've used the word 'corrupting,' and I want to be very clear about it: I mean by it not the corruption of individuals, but a corruption of a system itself that all of us are forced to participate in against our will.
