Ellen Belcher, who's filling in for Emily McCord, interviews Richard Vedder, the author of a new study advocating that Ohio become a "right to work" state. Next year Ohioans could vote on whether employers can require their workers to join a union to get and keep their jobs. Twenty-four states have "right-to-work laws that prohibit that practice. Vedder, a conservative economist who teaches at Ohio University, says that if Ohio had adopted a right-to-work law in 1977, a family of four today would be bringing in, on average, $12,000 more annually.
