Is it really worth it though? I'm not saying medical advancements aren't great, but one needs to realize that we can't continue to be the ones to bear all the costs of these advancements. And if others aren't willing to also bear the cost, then that is a clear indicator that economically, people don't want to pay for the cost of these advancements (ala, they aren't actually worth what they provide).
in my opion, it is worth it. let people who have the money pay for the advancements that will eventually help everyone. the other option is the slowing of medical advancements and we all get the same treatment, but worse cause the lack of advancements. or one where some people have better care than others, but those others are still better off due to the advancements made by those who can pay for it. So its we all suffer worse treatment, but equal, or we let some have better treatment, but with it they bring up the others as well. People do want to pay for it, those that have money, the problem is this is seen as unfair to those who can't. its not that the advancements aren't worth it, they just cant be given to everybody so they are not seen as equal. Maybe I am not explaining it very well. I'll try for an example, but dont bust my balls if its not good.
Lets say 2 people have a life threatning disease, 1 rich, 1 poor, the rich person can pay a lot of money to research and find a cure for their disease, but the poor man can not so they suffer and pass away, the rich person gets cured. Now that the rich person funded this research and cure, its cheaper for the next person. So although the first poor person did not benifit and was not treated the same, the next will, and so on and so on.
Lets say 2 people have a life threatning disease, 1 rich, 1 poor, the rich person is not allowed to have access to treatments that others cant have, so he doesn't fund the research to cure his ailment and instead is treated by the current methods. No advancement is made, but both people were treated equally.
So in one scenario people are treated equally, but at the sot of advancement, in the other the one with more resources gets better results, but those results filter down to help others.
Its a quick example but i think it works. Basically if there is no profit, no carrot, why will people put effort into it. Yes government will, and some people will, but I think rich people who value their lives will put the most effort and money into it, thus lifting more people to higher standards although not equal. (equaling out the rich and poor can be another thread :) )
