the numbers are much more complex than that, thats McBurger's Corporate Profit, which is derived largely from franchise fees, supply markup, and licensing deals. the McBurger Corp runs relatively few eat-em-up joints.
McBurgers Corp charges various burger stands for the right to use their "Brand", use their operations manuals, access their supply chain, and use their marketing machinery.
McBurger's business model is the top end of their McEmpire, strictly high order management, supply and marketing
the rubber hits the road at the franchisee who employs the labour, pays the local state and federal taxes, the business license, submits to health inspections and buys all their supplies from McBurger Corp.
when costs go up at the sales end, it's the bottom level guy who gets kicked in the berries and has to eat the costs, or fold up shop, losing his entire investment in the franchise, and then he has to start over from nothing.
McBurger Corp is only interested in keeping their franchisees in business so they can collect their lucre, but in the end higher minimum wage costs wont do shit to McBurger Corp directly, cuz they can always shift to a new distribution avenue for their products or change their business model.
it's the guy at the bottom, running a burger stand or two thats gonna get pinched, even if you believe in macro-economics and "aggregate demand"
