Had to respond to this directly!
Much as I respect you Laura and I'm sure you aren't implying that half the world is mediocre, I do take offence at this.
I can't be bothered to dig out the stats (but will if pushed

), but in countries where there is free healthcare for everyone the overall health of the population is better and mortality rates are lower.. everyone benefits.
Even here, where many argue for lower taxes and less government spending, no-one would suggest scrapping the NHS - it's just so beneficial to everyone - rich and poor. Even if it is shitly run sometimes and often wastes money... better that than be having to satisfy shareholders or being wheeled to a payment counter after seeing the doc (as I was in Thailand).
It seems it's an ideological thing - should we look after ourselves or should we look after each other?
