That on most countries of the world exist taxes that goes directly to Healthcare. This way hospitals always get money, doesn't matters if people are healthy or dying, always get the same amount of money.

This is most definitely not what happens, you have zero fucking clue what you are talking about. You think governments just cut a monthly check to hospitals in other countries? This is like a kid trying to explain a car by saying that gasoline gets ejected from the tailpipe and propels the car forward, not knowing what an engine is. Why even make shit up on the internet? For sweet upvotes? Why????? You obviously haven't interacted with healthcare systems beyond using it, so why go on the internet and write definitively on something you don't know?

This shit pisses me off because invariably someone who reads this is going to go spewing another even more bastardized version of the truth. Like the coronavirus.
