Minimun wage

Some states and cities have or have plans to raise the minimum wages to $15/hour.  In July, the House of Representatives passed legislation to raise the federal minimum wage to $15/hour. There also have been many protests (especially in the fast food industry) over the past 2 years about setting a $15 minimum wage. Amazon has raised its minimum wage to $15, Target plans to have a $15 starting wage by 2020, WalMart is working toward $15, and Senator Sanders (Vermont) has been pressuring companies to raise their minimum wages to $15/hour. Discuss and analyze the economic implications about this topic. How does the political aspect of the debate affect the economic analysis?
