What you call ‘Obamacare’ is really nothing new in my country. We’ve had various systems for many decades now, and they are similar to your ‘Obamacare’. It simply means that everyone is obliged to have a basic medical insurance. Additional insurance is optional.
I hear terrible stories from the USA about people not being able to pay their medical bills, and either becoming indebted beyond repair, or avoiding treatment because it’s just too expensive. That’s one thing that doesn’t happen here.
We chose the obligatory insurance road. Another road would be to provide basic medical treatment for free, and pay the doctors and the hospitals through taxes. The insurance road proved to be cheaper for society than the tax road. Therefore, we have ‘Obamacare’ for as long as I can remember, and we are actually quite happy with it.
