This week we've been asking listeners to suggest big ideas on how to fix the economy. We've discussed raising inflation, boosting housing prices, and capping total compensation for CEOs at $5 million. A few Takeaway listeners called in to offer one of their own: legalizing marijuana. Some say the government would save billions of dollars a year by not policing and prosecuting marijuana crimes, and that legalizing and taxing pot would bring in billions of dollars. We're consulting Harvard Unviersity economics professor Jeffrey Miron about whether or not it's an economy-saving idea.
