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.
