The government is offering a free I-Pod to any man with one child who will volunteer to have a state sponsored vasectomy. Well, probably not, or not yet at any rate. As the budget approaches, rumours abound, and there is speculation that there will be a huge purchase tax hike on large family cars, maybe as much as £2000. Tax the Chelsea tractors, the Porches and Ferraris by all means. But not this. This is a tax on children.
