“You haven’t shown me all possible taxes in Europe that go towards healthcare. Maybe such a source does not exist, which makes it suspicious that Europe would want to hide that knowledge.”
The British Medical Association [of doctors] will tell you about the underfunding of the NHS for as long as you care to hear it, and more.
Then you should be able to show it then. You haven’t done this.
Even if you showed this it doesn’t justify the idea of using people and using them up for personal benefit.
