America's problem are similar to elsewhere: to too much demand, overworked staff, long lines . There are tons of articles about problems with the NHS
The NHS is not a particularly good example. I live in another Western European country. It's easy to get an appointment quickly and an appointment means an appointment (if the appointment is at 11:15, you typically have to wait 10 minutes at most). My experience has been the same in another Western/Northern European country when I had what turned out to be kidney stones when we were on vacation. It used to be different when I was young, but the system was made more efficient.
Both of my parents were/are dealing with a severe illness, but both were quick to get appointments for tests/surgery and they haven't paid a cent.
Where is that?
We just went through 14 years of Tory government who are ideologically opposed to the NHS.
