The overall US healthcare cost per capita is around double the median of affluent Europe typically; higher than double vs Britain, and lower than double vs eg Switzerland or Norway.
A lot of US healthcare is covered entirely or partially by employers. If you're a software developer making near or over six figures, it's very common that your healthcare costs are covered by your employer.
What you're talking about when you say "100" for Holland is subsidization by way of taxation for covering healthcare costs. When you say it's free in Spain, you're talking about subsidization by taxation. Around 1/4 of the US population also gets "free" healthcare (ie the higher income brackets are paying higher taxes to cover those people).
US healthcare is artificially very expensive, for numerous reasons. The employer provided system can also make unemployment quite risky, definitely. There is no free lunch however, someone is paying for the healthcare in France, Switzerland, Germany, the Netherlands, and so on. Whether it's $7k (Germany), $8k (Switzerland), or $11k (US) per person, it's a lot of money.
