Right-to-Work States: 7, Forced-Union States 0
What are the main economic differences between right-to-work states and forced-union states (see map above)?
Not much really, except that compared to forced-union states, right-to-work states have had faster economic growth, lower unemployment rates, greater employment growth, higher state real GDP growth, greater growth in personal income, higher population growth, and greater home price appreciation. That's all.
James Hohman at the Mackinac Center has the data.
