Minimum Wage

an argument against raising the minimum wage is that the price of goods/services will go up to compensate. I disagree. If we imagine that wages went up 2 dollars an hour, then the average bottom of the barrell worker would earn an additional 80 dollars a week, or 320 a month. Where will businesses make up that much money? I doubt McDonald's would change their dollar menu items to dollar-and-a-half items, and if they did would they make up enough of a difference to compensate their employees wage increase? Suppose they could make it up by doing so, does it negate the difference in pay for minimum wage? I don't think so- I bet that the increase in price for products would be minor enough that the minimum wage employees do see an increase in money in their pockets at the end of the month. Maybe not the entire 320 dollars, but more than what they usually kept.
