For all hospitals, private and state, including all room and service charges? Or just for pharmaceutical charges, which is meaningless as it's only part of the charge?
Then do so, with definitive links to support them as I and others have had the courtesy to give definitive links to you, instead of just saying what you "can" do but not doing it.
Quote any - any at all.
As for "why", without examples I'm hardly in a position to comment on either your fantasies or your inadequacies.
If you'd explain what's wrong with the several examples you've already been given, by myself and by others, which cover dual pricing by both nationality and by residence, supported by definitive links, then I'd be happy to.
If all you can do is dismiss them on the basis that you haven't "seen" them or that's not what you've "heard" then I may as well try explaining Pythagoras' theorem to a house brick.
I can guarantee you that there are no discounts for Dutch residents at museums and that transportation rates are the same for residents and tourists. There is no museum who has the right to ask you for your passport, and for transportation companies it is the same. Nobody will ask you for an id.
I think hell will break loose as soon as private companies start asking people for their nationality and then charge them different rates. In NL this will be seen as unacceptable behaviour.
City governments can ask for a tax from tourists. Usually this tax is collected by the hotel where you stay. Usually this is about E 1 or E 2 a night. This is not a good example of dual pricing. Citizens of a city also pay tax, even more. So as a tourist you even have an advantage.
I can give you the names of many EU countries where tariffs for healthcare are regulated and the same for every hospital.
Why do I see so much messages from you where you bring things as facts, but where you are talking nonsense, because what you say is factually not right?
