I am replying to this hear instead of derailing the Trump thread.
I have a wife that worked 16 years in the NHS and is now in her 17th year working in the US system. Her mother worked in the NHS for many years after we left, and obviously all the girls she trained with are still in the NHS. I have also been a consumer of healthcare on both sides of the pond, with 3-4 surgeries in the US. Our experiences totally contradict your assertion that the healthcare in the US is average.
The healthcare is the US is very good for people with insurance, which is most of the working population. You definitely do not have to be rich to receive very good healthcare over here. I would say most people on average earnings or above get better healthcare than they would receive in the UK.
US healthcare is a service whereas the NHS is an entitlement. They both have good and bad TBH. There is no shortage of money in the US system and the facilities and equipment are generally years ahead of the NHS. I would give the NHS the nod when it comes to the quality of the nurses and doctors but the access to more readily available technology like MRIs and labs help balance that out.
Here are some polls for the NSH and US healthcare which might surprise some people:
Overall Satisfaction with US Healthcare was 65% in 2016:

Overall satisfaction in the NHS was 63% in 2016

Now for a little anecdote. My Mother-in-Law has skin cancer and she has been waiting several months for a NHS appointment to have suspect areas of skin removed. As of today she still has no appointment and this has been going on for over four months. I also suffer from the occasional suspect area of skin, I have one now. I called my dermatologist and booked an appointment for next week. Any procedures required will be performed during the visit. If I don’t like that dermatologist I could switch to the dozens of alternate doctors in the area with a simple phone call. In this instance the NHS is failing my Mother-in-Law pretty badly, whereas I am getting exceptional healthcare in the US.
The downside in the US when you have insurance is more paperwork and having to pay copays and deductibles. On the flip side tax is much lower here so you really don’t end up paying anymore for healthcare than many working Brits do.
