No, it's not sarcasm. If a business can't afford to exist without abusing workers by paying below a living wage, that business's business model needs to be rethought. If that means people don't get unlimited breadsticks and have to pay a little more on the check, then that's what it means. And, I do mean "a little more": McDonalds workers in Denmark make at least $20/hour, get excellent benefits, and a Big Mac costs a whole $0.27 more than in the US.

It's incredibly frustrating to hear well-meaning but misinformed progressives argue for policies that would make the lives of people I worked with and respect much harder.
