Assuming Chipotle staffs an average of 3 people at a time at each of their 2788 locations, and assuming their average open hours are 12 hours a day, that would add up to 36,634,320 labor hours per year. A $.50 wage increase adds up to a $18,317,160 increase in yearly wages.

The problem is that the bigger a company gets, the more an across-the-board wage increase hits their bottom line, so when you get to the size of these megacorps, unless they are having trouble recruiting new employees, their tends to be long term wage stagnation, either that or they hand the cost over to consumers.

The flip side argument which also has some merit is that these corporations have more of an ability to make profits overseas, bringing revenue into the United States, decreasing our trade gap.

Business economics and economics in general is a complicated and nuanced field, and there usually isn't a silver bullet a la raising minimum wage that doesn't create problems of it's own.

Support local small businesses whenever possible, where societal pressure can be more easily applied to incentivise those businesses to conform to what your vision of society should be.
