Do you have research based evidence for this please?
I have worked since 1981, mostly as a higher rate tax payer. I've had three NHS births - the first was mismanaged resulting in a prolapsed bladder for which the NHS refused to refer and put right, the second (excellent care) but the baby died which was expected, the third was fine because I'd learnt how to advocate.
Prior to children, I was diagnosed with rampant and serious graves disease, which my NHS GP had dismissed - three times. Sorted privately.
I have had a bad break repaired on the NHS and physio afterwards.
My osteoporosis care is via NHS rheumatology.
The NHS refused to refer my children for grommets.
The NHS, CAMHS, refused my daughter aupporpt when she was cutting. Overdosing and restricting food. She got better because with a combination of BUPA and private money there was £8k to spend on her. She is now a teacher, paying tax, and would not be doing that if left to the NHS.
Whilst I think three weeks is OK for a aroutine mammogram, the NHS is absolutely NOT free and is barely fit for purpose.
Similarly my mother has had one child, one heart op, is 89 and has certainly paid in more than she has taken out.
I'd like to see an NHHs passport that starts at birth and logs what each individual puts in and what they take out.
