As part of a project called "Buy Young," organized by the non-profit Our Time, over a hundred young men and women -- almost all of them under the age of 30 -- sat at a giant rectangle of wooden tables at the U.S. Chamber of Commerce headquarters building in Washington DC. They described how they came to start their own businesses, with explanations from "no one would hire us" to "there weren't enough women restaurateurs in New York City" and "I'm from a family of entrepreneurs." With names like Tutorspree, Jack's Threads, Tasty Clouds Cotton Candy and uBeam, their companies -- ranging in size from a handful of employees to many hundreds -- shout that they are different.
