Well, when I said free, I of course meant paid through taxes that are adjusted to your income level. Here in Spain your public healthcare quality won't change depending on if you make €1000 or €4000. You won't be put on top of a medical waiting list because you contribute more taxes wise to the system.

Dentistry is another thing altogether.

Also opting out of "public health insurance" is impossible here in Spain, because it's a right. You can however choose to get private insurance/get treated by a private healthcare company.
