What is to be done about all those assurances that governments have provided for generations about state-subsidised security in old age, universal health provision (in Britain, almost uniquely, completely free), and a guaranteed living standard for the unemployed?

We have been pretending – with ever more manic protestations – that this could go on for ever. Even when it became clear that European state pensions (and the US social security system) were gigantic Ponzi schemes in which the present beneficiaries were spending the money of the current generation of contributors, and that health provision was creating impossible demands on tax revenue, and that benefit dependency was becoming a substitute for wealth-creating employment, the lesson would not be learnt. We have been living on tick and wishful thinking…

The hardest obstacle to overcome will be the idea that anyone who challenges the prevailing consensus of the past 50 years is irrational and irresponsible. That is what is being said about the Tea Partiers. In fact, what is irrational and irresponsible is the assumption that we can go on as we are.
