Why do those people seem to disagree so thoroughly with what you seem to say?
I can try to answer your question, but I don't expect much from your reply. Frankly, people reply in twitter as they do because they are proud of their country and feel insulted. I can tell that current american leadership is not very popular here at the moment. Not that I would support it either.
Before we ended up in this stupid argument over Finnish healthcare, I tried to contribute to the original topic of this spin off thread (differences in healthcare systems) since I have some insight into this having worked in the field both in Finland and in the US.
My point was, and still is, that claims like the Sanders tweet are overly populist and uneducated. (Haley tweet was really stupid too.)
There are a lot of misconceptions about US medical system in europe and even more about Finnish system in the US.
Most insured US patients would never accept the level of service in Finland, with long waiting times, no possibility for second opinions and limitations in access to some advanced diagnosis and treatments. A growing number of Finns don't accept it either, with a surge in private health insurances. This creates a problem of double expense. First in taxes, and then in insurance fees.
Childbirth and maternal care are one of the success stories in the Finnish healthcare. No doubt about that. Yet, 2/3s of families feel they need private insurance for their infant. On individual level the fine statistics don't help.
A comparable price in a Finnish hospital for an uncomplicated delivery is btw. 2300-3600€. When you compare this to the $12000 American counterpart, there is no obstetrician involved in the price, it is the price for a straightforward uncomplicated delivery handled by midwifes. You don't know which hospital you are assigned to until the delivery starts and you are allowed to call the service hotline, and you don't know (and can't choose) who will be responsible for your care. These type of differences explain the price difference.
I also know that most insured americans do expect more personal care and choice.
