Labor unions have dramatically declined as a percentage of the American workforce over the last 30 years. A new proposal from presidential candidate Bernie Sanders seeks to double union ranks, City Journal senior editor Steven Malanga reports, which would mean adding nearly 15 million new members. Malanga joins associate editor Seth Barron to discuss Senator Sanders's proposal, which would put new restraints on employers, limit workers' rights to opt-out of union membership, and make other changes to U.S. labor law. The Sanders plan would also give federal workers the right to strike and force states to allow government workers to unionize.
