This week, CNBC is counting down America’s Top States for Business.

On Monday, CNBC’s Scott Cohn reported from No. 5: North Carolina, a right-to-work state. On “Power Lunch,” Mark Mix, president of the National Right to Work Committee, and Marybeth Maxwell, director of American Rights at Work, joined Cohn and CNBC’s Bill Griffeth to debate whether non-union states are better for business.
