Americans do not care about Americans, and there is no way to design a working system if Americans don't want it because it benefits Americans.

As other commenters have said, pre-existing conditions could and should have been handled separately in a single issue bill, separate from existing insurance. Instead, the truckload of regulations that was brought in around Obamacare has buried health insurance in the US in depths of inefficiency.

Its absurd to drive multi-ton flaming trash truck when all we originally needed was a scooter.
