Worse, they will call you a liar if you attempt to say higher minimum wages result in increased unemployment.
True, but that's par for the course with anything these days, on both sides of the aisle.
The best thing you can do is tell them, “Look, I personally don’t support the minimum wage laws because I don’t think they accomplish the goal that people expect but since you DO support the minimum wage law my question to you is why are you only asking for fifteen dollars an hour, why don’t you ask for fifteen hundred dollars an hour so we can all have mansions and yachts?”
