This is an item where the govt cannot win so previous governments (including Thatcher) have pretty much left it well alone.
As soon as you initiate any reforms then someone must lose out and the press will then happily post pictures of wheelchair bound people chaining themselves to the railings at Westminster.
But the problem is that we're up to our eyeballs in debt and simply cannot afford to continue with the status quo. So something needs to be done. Someone must lose out. Or we all lose out eventually as the weight of our debts will just collapse us.
We do need to support our vulnerable and sick but its where you draw the line that's the hardest. We simply don't have a magic pot of money. What we did have has run out so something has to give.
I don't envy whoever has to make the decision at all.
