No, not the sort wealthy middle class kids have between college and work (coming in to our boosktore, buying a travel book on exotic destinations like Australia or Brazil and then having the cheek to ask for a student discount! If you can afford to go on holiday for months halfway round the world you don’t need a discount, bugger off!). No, the sort of gap between rich and poor. New research shows the gap in life expectancy between poorer Scots and the nation’s wealthier citizens is now almost 20 years. So much for equality.
