I'm sorry but that's not really the issue here. They aren't trying to give anyone a raise, they want employers to pay minimum wage to people who work for them. You see, free market systems don't really have a magical hand guiding them to the best possible outcome every time. In this case, companies need a nudge to pay their interns because job markets have made experience more valuable than the degree the students just earned. Otherwise students jump on the opportunity to become near indentured servants, if it means they might get hired on for pay later on.
