So who DID pay for the treatment? And how much did it cost?
I'm sure it take decades of research and FDA approval costing, on average, nearly a billion dollars to bring any new drug to market. I see the article states she is in an immunotherapy study so I'm guessing that Capitalism is funding this. Venture capitalists buy stocks in bioresearch firms. They then short and use options to manage their risks as the majority of studies will fail to achieve good results.
Socialist systems are not capable of doing this type of cutting edge research. However, I have heard some people say that Europeans are the FDA's favorite lab rat.
It says she is a working MD in the article. At least she makes some contribution to her care I imagine unlike the invaders who get it all free on the taxpayers.
I image her treatment is paid for by the same people who pay for the medical care of illegal Mexicans.
