because they can afford it?
		
		
	 
Right, there are two children, one born into wealth and one born into poverty. Why should the wealthy one be able to have better healthcare than the poor one? What has the poor child done to deserve worse healthcare?
Further, say one operating theatre can be used for all sorts of surgery, ranging from cosmetic to life-saving. Why should a slot be able to be purchased so that miss moneybags can get a slightly reshaped nose or something to that effect, thus preventing a poorer person from undergoing lifesaving surgery? There are some things that shouldn't be determined by who has the most money.
	
		
	
	
		
		
			The assumption you're making is that everyone under a single-payer system would receive the very best health care possible, when these socialized medicine systems have proven that the amount and quality of care would decline.  If we socialized our system, it would be even worse, as most of the world's medical innovation occurs here.  And it sounds cruel, but if you are only compensating your physicians $75-$100K, the number and quality of physicians will decline.  
There is always a tradeoff between security and freedom.  When the government can tell you what health care you can receive, they have the power of life and death over you.  I'm willing to trade off having to sell everything I own to get whatever health care I can afford rather than to have my life controlled by someone else.
What freedoms are you willing to give to never have any worries?  I went through childhood, where my every need was taken care of, but I was controlled by my parents.  I'm an adult now; I make my own choices.  I prefer being an adult to being a child.
		
		
	 
I go on the school of thought that a lot of doctors don't become doctors on the basis that they want to earn as much money as possible. For example, then there would be hardly any doctors in the UK, as prospective doctors could choose another degree and then end up a highly paid banker. I believe that people are capable of acting upon other factors than money. Some people are willing to serve humanity for "lower than market price", and many doctors fall into this category.
I don't see why competition should encourage medical innovation. There are enough very clever scientists that would strive to provide the best they can for humanity even if there wasn't a race for who could produce the vaccine fastest. In fact, if the companies pooled resources rather than worked against each other, there is an argument that innovation could take place faster, as people working together are more efficient than people working against each other.
On the topic of the government being in control of my life and death; to an extent I'm okay with that. It's a very, very tricky situation, don't get me wrong, and I haven't been in a situation like that in my life. However, it's not exactly in the government's hand; individual doctors who are trained in that field make the call. I'm sure I would rather die than have my life prolonged by a month or two or extreme pain at a massive cost to the government. 
From stories over here in the UK, there are very rarely problems surrounding "pulling the plug" and often they are essentially parents wanting to prolong an essentially brain-dead baby's life at extreme cost to the taxpayer. The baby would have no quality of life whatsoever, and it is just prolonging the inevitable by a matter of weeks or months. 
This is a really awkward situation, but I often think that an objective jury, for example, could make a better decision than the family of the person who is almost dead.
On the subject of freedom, I'm OK with having that limited by the government's role, at least to some extent. We vote for the government, and in general they act in the way we want them to. It is in their interest to act in the way we want them to, so that they can stay in power; so in theory a balance should be met.
