People who feel the world is tilted against them will spawn the kind of hatred that is very dangerous for all of us. I think it's a healthy sign that there are demonstrators in the streets. They are raising the question of 'is the rich world giving back enough?'

When a country has the skill and self-confidence to take action against its biggest problems, it makes outsiders eager to be a part of it.

Make sure people get educated, help out with health emergencies. Those things, the government should do. That's 96 per cent of the economy, those two sectors.

The world today has 6.8 billion people...that's headed up to about 9 billion. If we do a really great job on vaccines, health care, reproductive health services, we could lower that by perhaps 10 to 15 percent.

Whenever there is hard work to be done, I assign it to the laziest man as he is sure to find an easy way of doing it. Be lazy, think crazy.

R&D generally has been a bipartisan thing, because in the IT space, in the medical space, the U.S., the benefits to ourselves and the world and our economy have been very, very clear. I'm hopeful we can make a very strong case there. Energy is actually harder; it takes more time to get a product, but if you do it's a very, very big market and the constraints of doing that in a clean way are more obvious all the time.

The general idea of the rich helping the poor, I think, is important. That your sense of justice says, why should rich kids - who barely get these diseases and almost never die of them - why should they get the vaccines, when poor kids, who actually do die from these diseases, don't get those things? It's an unbelievable inequity that there isn't that access.
