What you are referring to " was warned about by those evil republicans " is called projecting - and even foreshadowing of their actions. More in the tone of " if you do this we will do that ".
I'm not saying that republicans are actively setting up the "panels" as referred to them - but they are the #1 reason why we STILL have the only for profit healthcare system in the modern world.
And as someone a few comments above mentioned - there has to be some point of reality applied (how much is it worth to extend X's life by Y length? and when is that unbalanced and unreasonable?
But all a for profit healthcare system is going to do is ALWAYS drive up the costs, because they gotta make their money, doesn't really matter the impact on individuals (or the population really).
So under a For Profit Healthcare System - which Republicans fight tooth and nail to keep vs. going single payer Public service like the rest of the modern world - the cost of services will be significantly higher and incentives to help people lower and ultimately it will kill more people - period.
