Ayaan Hirsi Ali, my hero, sings the praises of open markets in a tightly edited, 6-minute video on the Templeton Foundation site, part of a series of discussions about “big questions” such as “Does the free market corrode moral character?”

English is at least her fourth language — she was born in Saudi Arabia, came of age in Kenya, won election to Parliament in Holland, then fled to the United States in the face of Islamic death threats — and yet the 39-year-old Ali provides one of the most powerful descriptions of the virtues of capitalism that I’ve heard anywhere. A remarkable person.
