Surprised to hear that. You seem to be a logical person in general, I figured you would understand that insurance is a business. Taking on pre-existing conditions is a terrible way to make a profit. It's basically saying you agree to lose money. I get the whole "people before profits" and all that, but at some point a business has to be profitable just to...ya know...stay in business. Whether they pay out more than they take in, or cut profits to such a slim margin nobody bothers with it anymore, it's a recipe for disaster for most of us in the long run.
End result will be full-blown nationalized healthcare regardless. Lets go ahead and get it over with.
