Here's an MIT economist explaining how "job lock" resulting from the need to maintain health insurance cripples the American economy and entrepreneurship:

"The type of universal health insurance coverage policy proposed by President Obama will clearly promote the freedom of workers to leave their jobs to start new companies. By solving a major impediment to mobility in the U.S. labor market, a larger government goes hand in hand with more business development. The next John Galt may owe a debt of gratitude to this pioneering effort in universal coverage."
