How Fully Private, No-Insurance Hospitals Help the Common Man

How does one make an economic decision when the price of a good is not evident? To any adherent of the Austrian school, this of course is impossible. There is no way to decide whether to purchase something if the only way of knowing the price is after committing. For example, who would fill up their car only to see what the price was at the end? No one. In no aspect of life would this make sense, yet it is the standard in the American healthcare system.
