The Burning Man festival is a weeklong celebration of anti-consumerism, but it's also a model that many businesses can learn from, writes E.B. Boyd. The festival works because it trusts attendees to behave well, and it gives them latitude to unleash their creativity, Boyd writes -- principles that many business leaders would do well to emulate. "Trust people and they will usually live up to that trust. Give people creative freedom, and they will surprise you with what they deliver," Boyd writes.
