Then I guess we have to continue tobacco farming.<quoted text>
So you can't really define "living wage"; don't feel bad, no one else can either, which is why everyone is in disagreement. Adding in a few of "life's pleasures" makes it even more ambiguous. The poverty level is an arbitrary number the govt comes up with. To be meaningful it would have to be different for every state/city/locality because the cost of living varies so much from place to place.
Though I agree fast-food is horrible for you, if fewer people are consuming their product, that means fewer workers will be needed, which means someone is getting fired, which is NOT exactly a better deal for employees.
Let the free market work it out.
The govt shouldn't be dictating a minimum wage any more than they should be dictating a maximum wage.
My problem with your analysis is that it makes a case for slave wages. We have had raises in minimum wage in the past, and despite all the fear mongering, the sky didn't fall. I think somewhat higher prices for these dungburgers would result in very little loss in the marketplace.
