They do not deprive the countries of money. They deprive the governments. This is a _good thing_ as governments are notoriously more inefficient than private companies since they don't have any incentive for saving and investing, but to spend and buy votes for the next election.
Like how socialized medicine provides better care at a third of the cost of a system based on profits and insurance?
When comparing what to what? The American medical system is as far as it can be from free market without being socialized. Between RX, now mandated insurance, tax distortions, billion dollar FDA approval process, AMA certification (enforced by government), etc. it is all a big clusterfuck of inefficiencies and monopolies imposed by government. They just assume people are to stupid for their own good and then need a daddy government to treat the smallest infection.
Heck the cost of approving a new medicine is so high that government essentially ensured nobody can enter the market. This is why in my original post I said "Except when government is involved".
Compare that to healthcare that is not government controlled such as lasik and plastic surgery. Both the cost goes down every year and quality goes up.
Socialized medicine is a disaster everywhere. You often need to wait months for an appointment, lack of medical equipment is very common, people often end up going to emergency for small things only to wait hours because medics are treating true emergencies. This is something I speak from experience being from a country with socialized medicine. But please note I am not advocating the american system either.
But this went already far enough from the original topic, so I am out.
