Interesting questions have been raised about whether Mitt “retrocatively retired” from Bain so he could keep his wife’s health insurance coverage while she underwent treatment for MS. The Romney campaign won’t respond, which gives us a license to speculate. Of course, Romney is one of the few people who could actually afford to pay for MS treatment out-of-pocket. But given his aggressive efforts at tax avoidance, one suspects that he doesn’t like to part with money if he can help it. Unless he’s buying a car elevator for a ridiculous beach house.
