In this case the costs would be burdened by those outside the single payer system.So do some people think pharmaceutical companies should be part of this deal, what about all the OTC drugs, do they fall under this umbrella too? Will we still be able to buy OTC's and will they be regulated too? It was already mentioned about marketing these kinds of things but if you take away the payers/buyers (however you want to look at it) then where does all the competition go? If all these companies don't have to compete anymore then what is the use of all of them to be here.
A lot of profits from hospitals and specialists practices are used for research and development, same goes for pharmaceutical companies. If you start taking away their profits with reduced costs then who is going to pay for that?
