WSJ Interviews Bill Gates: Was the $5 Billion Worth It?

Thanks to Will for passing this along.

A decade into his record-breaking education philanthropy, Bill Gates talks teachers, charters—and regrets.

'It's hard to improve public education—that's clear. As Warren Buffett would say, if you're picking stocks, you wouldn't pick this one." Ten years into his record-breaking philanthropic push for school reform, Bill Gates is sober—and willing to admit some missteps.

"It's been about a decade of learning," says the Microsoft co-founder whose Bill and Melinda Gates Foundation is now the nation's richest charity. Its $34 billion in assets is more than the next three largest foundations (Ford, Getty and Robert Wood Johnson) combined, and in 2009 it handed out $3 billion, or $2 billion more than any other donor. Since 2000, the foundation has poured some $5 billion into education grants and scholarships.
