My last experience with UK healthcare was a few years ago.

My mum had a ruptured bowel which ended with a permanent stoma.. She also had a stroke during surgery.
During the time she was hovering between life and death my father (80) had a complete breakdown in which he stabbed himself 6 times.
He was placed in a treatment facility for 3 months.
Between the two of them I was in the UK for 5 months.
The treatment they received was amazing.. they were they both hospitalized for months. The aftercare, from folk coming into the home to make sure they were both managing, eating properly, making sure their home was suitable for disabled persons, given any aids they needed ...I could go on.
All this at no charge to them.
I know that a big part of that system I would not like e.g waiting for non-urgent care, but, I dread to think how much debt they would have been in had they lived here.
I am firmly of the opinion that healthcare is a right not a privilege.
We are, or were, one of the richest countries in the world, our people should not have to go into bankruptcy because of medical needs.
