Joe asks about alternative energy? Any "earth changing" areas you're considering right now? Buffett says he usually doesn't try to make money by guessing that something that's a dream now will be doing really well 10 years from now. People will keep eating candy, chew gum, use Tide, 10 to 20 years from now. "I can't pick the winners."
Are soveriegn wealth funds bad? Buffett says they're inevitable, made necessary by fact that U.S. is sending so much money overseas. We must expect those overseas to "use those little pieces of paper" (dollars) in an intelligent way, which means investing them.
"People will think in dollars for a long time." Even though the U.S. dollar is getting weaker, it's still a very, very, very important currency and things like oil will continue to be priced in U.S. dollars in the future.
Back to emails. Larry in New York asks how shareholders can get accountability for CEO pay? Buffett says only the very largest shareholders can get through to the "big shots" on a company's board when CEO pay is egregious. Large shareholders, says Buffett, could be even more vocal. "I'm a big fan of pay for performance."
Allan from New Hampshire asks if Berkshire Hathaway wil change after Buffett's death. Buffett says less chance of Berkshire's coporate culture changing after his death than might see in other companies. He would come back and "haunt" anyone who made big changes.
