By "empirical fact", I meant that our socialized healthcare system here in France seems to do a better job than America's in two key metrics: cost (we dedicate a lesser part of our income to healthcare than Americans, through taxes) and life expectancy (ours is slightly higher).
The one caveat I would concede is that we have less access to experimental treatments for rare diseases, but we eventually get most of them. And at a better bargain than Americans too.
For electricity, we had a very cheap, clean grid thanks to our nuclear reactors. It started going downhill the instant Europe asked us to "liberalize" our national monopoly. "Private companies" began reselling electricity for a premium. These are essentially useless parasites. Price got up, all else equal.
As for housing, I know we already have more vacant homes than homeless people (from our national statistics agency). So the issue is only one of repartition. I don't care about any rationalization or gesturing about "market forces" or whatever. We ought to distribute housing to those that lack it.
I'll read your article, thanks.
