“With the relatively narrow profit margins in grocery, this amount is huge. To cover losses, grocers need to raise prices, so in the end, we all pay for grocery theft.”

Not at all, you see parallel to the bourgeois’ profit margin is what I like to call the proletarian consumability margin (real wages) which determines when a commodity is affordable or not, and guess what, that also runs with a very slim margin in this economy.

What will actually happen is as follows; As the prices raise higher to compensate for losses via theft, more and more consumers will be priced out of consumption and will then join the thieves, continuing this vicious cycle until a new paradigm in relations between classes is reached in this regard (lower prices, higher wages, increased social programs, increased criminalization of poverty, etc…)

The author seems to live in the past where everyone is a labor aristocrat still. These bandwagoneering arguments that group the workers interests in with the bourgeoisie will no longer resonate the way they once did.
