Being born into a prosperous middle-class family typically endows you with a safety net for life. If you are not naturally very bright, you are still likely to go far and, at the very least, will never experience poverty as an adult. A good education compounded by your parents’ ‘cultural capital’, financial support and networks will always see you through. If you are a bright child born into a working-class family, you do not have any of these things. The odds are that you will not be better off than your parents. Britain’s class system is like an invisible prison.
