We have an abysmal record on gender parity. Rwanda and Laos have more women in Parliament than Britain does. Businesses still are mostly run by men (though men created the financial disaster we are still trying to sort out). The USA has quotas for women in top jobs, so too do the Scandinavian nations. Britons hate the idea of positive discrimination - though that is what men have enjoyed for centuries. It’s time to get tough, argues top economist Vicky Pryce.
