In the cradle of American innovation, workers are making career choices based on co-payments, pre-existing conditions and other minutiae of health insurance. They are not necessarily making decisions based on what would be best for their careers and, in turn, for the American economy — that is, “where their skills match and where they can grow the most,” as another Silicon Valley entrepreneur, Cyriac Roeding, says. Health insurance, Mr. Roeding adds, “is distorting the decision-making.”

It is impossible to know how much economic damage these distortions are causing, but they clearly aren’t good. Economic research suggests that more than 1.5 million workers who would otherwise have switched jobs fail to do so every year because of fears about health insurance. Some of them would have moved to companies where they could have contributed more, and others would have started their own businesses.
