You'll want to listen to this interview with Indra Nooyi on the BBC. Nooyi is an immigrant from India who rose to become the CEO of PepsiCo. She is a proud American, and she makes that absolutely plain in the interview. She doesn't back down on the American work ethic or take the blame for obesity.
As an addicted Coca-Cola drinker, this interview almost made me want to take the Pepsi challenge.
