I'm not sure that asking the woman in the street what she thinks should be done with something like the NHS is helpful, and it is particularly unhelpful to suggest that unless we have a solution we shouldn't moan about the problems.
I have no clue about the pragmatics of running a massive organisation such as the NHS - how could I have? What I do know is that I support the principle of the strong paying for the weak (and the well for the ill), that I see the funding of that as the responsibility of governments, and that I do not accept that it is somehow the fault of all of us that we generally live longer than before.
Yes, the NHS can now do far more than it once could, and yes, we have an aging population, so demands on it are greater. But this could have been foreseen decades ago, and funding issues should never have been allowed to become a problem. Governments have allowed this to happen, and governments should sort it out.
