“Purely for the sake of health insurance, people stay in jobs they aren’t suited to—a phenomenon that economists call “job lock.” “With the new law, job lock goes away,” Arensmeyer said. “Anyone who wants to start a business can do so independent of the health-care costs.” Studies show that people who are freed from job lock (for instance, when they start qualifying for Medicare) are more likely to undertake something entrepreneurial, and one recent study projects that Obamacare could enable 1.5 million people to become self-employed.”
