There's a common sleight of hand in the political class' views of the NHS;
They (willingly) confuse growing levels of dissatisfaction with the NHS as growing support for privatised health care, but while people are now sometimes more willing to go private this is a strategy of desperation not a willing political conversion.
What voters actually want is for the NHS to work properly, fairly & efficiently.... and that can only be achieved with a renewed commitment to full funding!
