I'm in a EU country, in total I pay also around 15.000 EUR per year
People with lower incomes pay proportionately less, government employees and high earners can also switch to private insurance where they get much better service but for non-government employees this comes with risks and has to be done at a younger age.
OK, if its for a whole family, then yes: Germany is more expensive, I can see now - 27000 USD for a 4-head family is acutally quite cheep, if i add up those numbers?
Do you mean some more numbers or the link to a healthcare-cost-calculator?
