This video does a nice job of describing many of the economic arguments for and against raising the minimum wage in a comical way. The clip is a few years old, but it still does a nice job of discussing many of the common arguments. Note: the clip does include a supply and demand graph, but it labels supply and demand incorrectly! This is a good opportunity to discuss economic misconceptions, as well as the labor supply and labor demand curves.
Thanks to Rebecca Chambers for the clip and description!
