Entrepreneurship is transforming America—not just for a few, but for all of us and for the better. Consider: Today roughly 45 million Americans, about 30 percent of the labor force, run their own businesses. Sometime during their careers, well over half of university graduates will start a business. Most Americans today work in firms that have entrepreneurial teams in charge. And most U.S. job growth and new technology comes from entrepreneurial companies. In short, ours is no longer an economy of big, old, stable corporations. Yes, we have many of those. But increasingly, we live in an economy of new, rapidly growing (and sometimes rapidly declining) entrepreneurial companies. America is unique in the world, a nation rebuilding itself on the principles of entrepreneurial capitalism.
