Dumping every high risk person in the same pool cant survive. The key is that everyone is entitled to health insurance at the same rate as everyone else.
Want to insure the healthy people, you have to insure the sick
The idea of health "insurance" for people who are already ill is absurd. The idea of "insurance" for events that have already taken place is actually pretty stupid. Warren Buffett won't sell you GEICO insurance if you have already wrecked your ride.
As far as Indigent individuals with high medical bills, I have no problem with providing private or even public charities to provide care to these misfortunates suffering in destitution. Addressing help that can be given to these folks stuck between a rock as well as a hard place is a worthy topic of public importance.
But it has nothing to do with "insurance" and shouldn't affect the relationship that I have with my own insurance family or personal physicians in the least.
