I'm in The Netherlands. I pay €5000/year insurance for two adults, on a discounted (via work) top care package. The excess is €385, the lowest level - actually this year it's more.
I can choose which hospital I want to use (not only ones the insurance company says) and I get fully reimbursed on most things, if I have to pay out of pocket in the first place. I pay about €417 per month. That includes physio and basic dentistry (checkups). Lenses are covered to €150 per two years. My actual lenses cost about €800 per two years due to a complex prescription...
Children are free.
Mental healthcare provision is better than the U.K. There are waiting lists, but not that bad. There are two levels of treatment. Level 1, which is your 12 sessions of CBT. Depending on your level of coverage, that is not fully covered. If you need more serious/long term care, that's Level 2 and is fully covered.
Contraception is not covered.
Most dental work is not covered.
There is an out of hours GP and that costs about €80. If you go for something that's not a minor emergency then you pay out of pocket.
It is a legal requirement to have Dutch health insurance. There are many cheaper policies - I think the cheapest is €100/month for students and/or higher excess. You cannot choose your providers freely with those policies - which means waiting times can be longer - and they don't include things like physio.
What people are not factoring in with insurance companies is collection of your health data. The insurance companies here collect information on your mental health treatment, for example. It's not anonymised. There are psychiatrists and psychologists fighting this, because it breaks patient confidentiality. At the moment they cannot use it he info to discriminate against you (as long as you can afford a policy, you're entitled to it), but I cannot see any other reason why they'd want it long term.
Also, the health insurance companies are involved in salary payment of medical staff.
And health insurance companies are involved/influence the government's decisions. During covid health insurance companies were complaining that they couldn't afford to pay out all the covid costs, for example. The government had to involve them at least partially, in discussions.
So while individual payment is an issue, there are much bigger issues involved when profit gets involved.
