The wait time is a complete myth made up by the US. It can take months in the US to get an appointment with a PCP - if you don’t get shunted to an NP or something instead. Then more weeks for any specialized tests like an MRI. Which you have to pay a good chunk for even with insurance. Then weeks for whatever’s next, or followup visits.
If it’s an emergency, like any country, you can go to an ER/ED and be seen at a time based on severity of need. Difference is other countries will charge little to nothing, but in the US you will be charged quite a bit. Even more if your insurers decide you’re “out of network” or some such, or if they don’t outright deny your claims anyway.
But for non-emergency tests other than basic things like blood tests that don’t appear to require prompt intervention? Yeah. Weeks to months in most places.
Just bullshit made up by Big Med and Big Pharma regurgitated by politicians on their payroll to keep your $$$ flowing into the pockets of multi-million- and billionaires.
