"The right-of-centre parties still often compete with left-of-centre ones to proclaim their attachment to all the main programmes of spending, particularly spending on social services of one kind or another. But this foolish as well as muddled. It is foolish because left-of-centre parties will always be able to outbid right-of-centre ones in this auction - after all, that is why they are on the left in the first place. The muddle arises because once we concede that public spending and taxation are than a necessary evil we have lost sight of the core values of freedom."
