No, it means to suggest that the number of people who have actually paid anywhere near $500 for a couple Tylenol pills is so small as to be an irrelevant rounding error in the grand scheme of things.

Note I said paid, not billed.

I never said that. If political walls make it impossible to reduce the 80% then do what is possible. All I'm saying is that 20% contributes to the solution.

I would imagine that farmers will start revolutions if you cut off their water supplies, while city folks won't care too much if the lawn isn't watered. 20% is an easy target... hit it first and slowly work on the other problem.
