I'll never understand why we pretend that things are this expensive.
USA, of course, because I can't imagine anywhere else in the world working this much harder and not at all smarter.
FYI, Medicare is our government insurance for older or disabled people and is paid for mainly with taxpayer dollars as well as "small" premiums by members.
It's not "for some reason". Dental was covered or heavily subsidized in Canada at least to 18 years old, until the conservative goverment convinced idiots only poor people without jobs need dental care. "If you work, youll have dental", and now they take it from our total compensation.
I have teeth and mental health covered through my employer, which sadly doesn't fit all situations that need dental and mental health (hence why tying insurance to employers is stupid).
I got a lot of teeth work done in the UK while I lived there on a Visa, and it cost almost nothing without employers insurance.
People complain about the american healthcare system because it's an oligarchy and oligarchs in other countries are trying to do the same. US just showed them with enough money and lies you can get there.
