Whenever someone I know makes a statement to the effect that the minimum wage benefits the poor, I always ask, "if a minimum wage of $7.25/hour helps the poor, why not make the minimum wage be $1,000/hour and really help the poor?"
Nobody has ever been able to answer that question and stick to that answer with further questioning. Oh sure, some have said, "because who could afford to hire anybody for $1,000 per hour?" So, then I ask, "how about $500? No? $100? No? $50? No? $40? No? ... $10 ...". Somewhere in this string they promptly either change the subject, create and knock down straw men, get irate and insist that my questions are absurd and have no merit, or otherwise indicate through their behavior and speech that they know perfectly well that some people who are employable at a lower wage are never going to find work at $7.25 per hour.
In other words, pretty much everybody knows that minimum wage laws don't help the poor. In fact, they are currently devastating the young poor:
Obviously, I think that minimum wage laws are really a bad idea. However, it has now crossed the line, in my opinion, into severely immoral. The government is now telling a large class of people that they are not allowed to legally work. These people, who can't find jobs, are going to be adversely impacted their whole lives because they are unable to gain experience that would've helped them find better jobs later.
