The cost has gone up significantly more than 7% in CA, but then minimum wage is not the only cost that has gone up for the franchise owner. Gas, Electricity, property rent, all if this is affected when wages go up across the board. Not only that, but when minimum wage goes up but my middle class income does not, I'm going to spend a lot less time eating out (and that's true). If the franchise owner wants to survive he's going to either need to raise prices or cut staff in order to make that happen if he has fewer customers.
Nevermind that though - are you really arguing that higher unemployment is a good thing? Really? Because, that's what is going to happen if you put a couple of franchises out of business. You know people own those franchises, right? It's not some big fast food monopoly - when a franchise goes under someone, a real person, is going bankrupt. I much prefer having as many options as possible and having the franchise owners have to offer higher wages to get the best employees - rather than forcing them to offer everyone the maximum they can and having higher bankruptcies and unemployment (and yes, higher food costs for me, the consumer).
Just me?
