question. there is the impeerical evidence, i'm wondering what is the argument that lower wages help business. >> the only way is to ignore the other side of the equation. then that sort of works itself out. if you are talking about the kind of businesses that employ a restaurant or grocery store. they are spending a third of income on labor costs. they have to find a way to provide the same product or cost. that is what the literature is showing. there were 28 states that raised the minimum wage.
