I guess my experiences have been different than this, so I'm not sure if its true. For example, my college roommate has had a back problem for about a decade. As a young lawyer he was unable to obtain private health insurance because of the pre-existing conditions when he was taken off his parent's plan. Could you elaborate on what you mean?
I guess this is a hypothetical that could be true. Do the elderly people that have been on government healthcare have a harder time with their disputes than with the current private health agencies? Given the problems that the other poster talked about as well as the ones I experienced, I guess I'm not convinced this is true yet.
