Bill and Melinda Gates of the Gates Foundation, the world's largest private philanthropic fund, sat down this holiday weekend with David Gregory on Meet the Press. Their extraordinary resources have allowed them to do everything from immunizing children across the Third World to donating tens of millions to American schools. "We're impatient because it often goes slow," the Microsoft founder told David Gregory, "and this is about saving lives and allowing people to achieve their potential. So the faster we can get new innovations out there, the better." Bill and Melinda make a strong argument on the important talking head show for increased funding for health research.
