Costa Rica has an affordable all inclusive public health care system (Caja). But you can also pay for extra for private healthcare. Is it the same in the UK?
In canada we’re in a phase where this is just starting. Private clinics (e.g. telus health) have started to pull doctors out of the public system and put them behind subscription paywalls. We’re still paying the majority of their salary, but they can only be accessed if you pay their private overlords a monthly fee.
