Guests at a high-dollar fund-raiser for Hillary Clinton were treated to cocktails, dinner and an hour-long business tutorial from billionaire Warren Buffett.Buffett, the founder of Berkshire Hathaway Inc and one of the world's richest men, co-hosted the fund-raiser, which brought in at least $1 million for Clinton's presidential effort.Buffett, a Democrat, has not formally endorsed Clinton, but guests at the dinner said he called the New York senator "the person to run the country."Buffett is also expected to host an event for rival Democrat Barack Obama later this summer, and has also spoken favourably about the prospects of New York Mayor Michael Bloomberg, a fellow billionaire who recently left the Republican Party to become an independent.Buffet joined Clinton on stage after the fund-raiser to field questions from attendees about his views on American competitiveness, smart investing, education and the nuclear threat.Central to Buffett's message was the notion that he and other privileged Americans, those who had drawn the "lucky tickets" had an obligation to provide for those less fortunate. "We have the chance in 2008 to repair a lot of damage," Buffett said. "We have a wonderful economy. The market system works in this country. Our problem is how we conduct ourselves in the world."
