Here is my back of the envelope figuring. As a rough estimate, I figure that a fast food worker can handle about 15 orders per hour, about 4 minutes per meal. If we give them an additional $7.50, that would work out to an additional cost of fifty cents per order.

That does not seem like all that much. Suppose that some enterprising soul decided to open a fast food joint and paid $15 per hour, passing on the additional cost to the customer. The advertising slogan could be something like, “We pay a living wage.” I think that out of guilt, I might be tempted to choose such a place over the other ones. I am not saying that they would dethrone McDonald’s, but there might be a niche market.
