My sister married a Dutchman and they have been quite happy with their system despite the high taxes.
My brother in law’s father is way better off with his government pension than our mother with social security.
But as I said, once the population changes and the attitudes toward a free ride change then it starts crumbling. And, I also think if they had to pay full price for their own defense it would strain their systems significantly.
Anyway, that’s just IMHO.
I think most Europeans have a very different view of freedom.
