This is tragic no matter how you slice it. It's also something that one must hate to make into a political point; but, it's gonna happen.
The NHS isn't free healthcare. There's no such thing as free healthcare. There's no such thing as free anything. If it were true that scarcity is a construct of capitalism and it could be done away with by nationalizing industries, this child could remain on life support forever and this wouldn't be a problem.
Scarcity is a reality of the world that we live in. Having governments in control of the resources just means that the government gets to decide when to pull the plug.
