You're still not providing a counter argument, just rejecting his argument.
The question you should be answering is: what figures do you think provide a realistic picture? And why do they convince you that the US model of healthcare works better than the Dutch model? You must have seen such figures (or if number don't do it, an in-depth impartial comparative study or something similar), otherwise you wouldn't hold such a position, right? So why not share that with us instead of just saying that the data he's basing his view on is wrong without explanation?
