Chicago has banned plastic bags from stores... Or so they want you to think. What they've actually done is require merchants to give out thicker, more harmful (for the environment) "reusable" plastic bags that people will likely just throw away anyway.
But the politicians appear "progressive" and the progressives (who already had their own reusable bags) can count a "victory."
This is when the paradigm of "Presentation > Content" breaks down. The presentation is disconnected and in fact contradictory to the content.
