With this historic budget, the Conservatives’ already headlong retreat from principle has become a rout: a great final leap into the void. For there will be no going back from this, for the party or for the country. Whatever the budget’s soothing talk of “temporary” this and “extraordinary” that, and for all its well-mannered charts showing spending obediently returning to its pen, deficits meekly subsiding, “investments” repaid in full, we are in fact headed somewhere we have never been before. We are on course towards a massive and permanent increase in the size and scope of government: record spending, sky-high borrowing, and — ultimately, inevitably — higher taxes. And all this before the first of the Baby Boomers have had a chance to retire, and cough up a lung.
