In the US, when I want to see my doctor I drive 15 minutes to get there and tell them I need to be seen for whatever and then I wait 15 minutes and then talk to the doctor. If they say I need to talk to a specialist, that may take 1-2 weeks after making an appointment though. It’s not cheaper, but at least I can get care when I need it.
Of course, not everyone can afford healthcare in our country. That’s the biggest problem. But it’s generally fast and competent.
