re: I’m convinced Bernie Sanders does not grasp the idea of profit margins

At least in theory McDonald’s, Walmart, etc, could get more sales if they raised their wages.

I’m met some people who claim not to shop at Walmart or eat at McDonald’s because of how low they pay employees. IDK if they’re telling the truth. But if there really are so many liberals who boycott those places, that probably does change the economic calculations of raising their wages a bit.
