Avik Roy: Last week, Vermont Governor Peter Shumlin (D.) announced that he was pulling the plug on his four-year quest to impose single-payer, government-run health care on the residents of his state. “In my judgment,” said Shumlin at a press conference, “the potential economic disruption and risks would be too great to small businesses, working families, and the state’s economy.” The key reasons for Shumlin’s reversal are important to understand. They explain why the dream of single-payer health care in the U.S. is dead for the foreseeable future—but also why Obamacare will be difficult to repeal.
