The best jobs in Britain today are overwhelmingly done by the offspring of privileged parents. Meanwhile, it is increasingly difficult for bright but poor children to transcend their circumstances. This state of affairs should not only worry the poor. It hurts the middle classes too, who are increasingly locked out of the top professions by those from wealthy backgrounds. Hitherto, both Labour and Conservative politicians have sought to deal with this problem by promoting the idea of 'equality of opportunity'. In politics, social mobility is the only game in town and old socialist arguments, which emphasised economic equality, are about as unfashionable today as mullets and shell suits. Yet genuine equality of opportunity is impossible against a backdrop of levels of inequality last seen during the 1930s. In a grossly unequal society, the privileges of the parents unfailingly become the privileges of the children. Thus, a vague commitment from our politicians to build a 'meritocracy' is not enough. Any genuine attempt at improving social mobility starts by reducing the gap between rich and poor.
