That's only true if you are one of those dopes who believes that price and profit can't be regulated.
The medical economy can work in one of two ways:
1) I have to lower prices as costs go down or my competitors will and I won't get any revenue at all and I'll go out of business.
2) I have to lower prices as costs go down or the government will slap me with a big fine and take away my license and I'll go out of business.
The reason (1) doesn't happen now is because the GOVERNMENT often gives medical-industry participants a patent or license that prevents competitors from getting into their field of speciality. Since it's the government that creates the scarcity and thus the opportunity for excess profit, then the government has every right to take its share of the value from that and either tax you down to a nominal yet lucrative profit, or fine you into lowering your prices to that level, i.e., system (2).
Right now, the people in the medical industry know full well that (2) can be implemented if the democracy only figures out that we have the power to impose it, so they spend a lot of money keeping the democracy from figuring that out. Not least by falsely demonizing government control of the economy (which they're only too glad to have in the case of the patents and licenses, etc.) and by generally tearing down government so it has little power to interfere.
And if a weak government and expensive healthcare mean more people are sick and the sick are more desperate, well, that's just synergistic with their goal of squeezing every last dollar out of anyone who prefers being broke to being dead.
