The fourth paragraph in the article explains LA already does it and lists every state. The first paragraph and the original title users the word "independently" to emphasize it was Chicago's choice and not a statewide mandate like LA.

Really, this should be fixed as a misleading change-of-title when posting to HN. Who can summon dang?

Title limit, I could not fit independently in. Propose a better title and I'll edit.

EDIT: "Chicago independently abolishes subminimum wage for tipped workers." May dang have mercy on my choices.

"Chicago abolishes subminimum wage for tipped workers" maybe?

I think it's a good edit. I don't know if it's a better title in general, but it avoids this major distraction.
