Wait weeks to see a GP, long waiting times to see a specialist or for treatment, rationing of access to technology like MRIs, and a risk of dying in a hospital car park or corridor, or being killed by an overworked A&E doctor.
Don’t get me wrong, the NHS is great, I love that Boris Johnson got more or less the same care in St Thomas’ that a homeless person would have received (perhaps a bit better).
But on an individual level, the FB engineer in US certainly has better care available to them than one in the UK.
