I'm currently living in an european country that has a national health service that supposedly ticks all the socialist talking points, including free (in theory) access to emergency care, but not only is the service largely inoperational with year-long waiting periods for surgeries, including cancer treatments, but also has a disgruntle workforce who systematically complains they are underpaid and overworked.
The situation is so appalingly bad that the national health service even routes patients to private hospitals and clinics, ending up paying a hefty bill for the services they were supposed to provide in-house but are largely unable to provide.
