I do know the price of a pint of milk, as I do the shopping. I did not remember the price of a value white loaf until I read about the controversy. I buy four crusty rolls in a pack in my local Co-op or a brown small loaf from a local supermarket when I want some bread. The lack of knowledge of items in the shopping basket by some MPs is more a commentary on who does the shopping in their households than anything else.
The truth is all MPs are in the higher income bracket just by virtue of drawing the MP’s salary. No MP has to eat a value loaf if they would rather have a dearer bread product. It does not mean ,however, that a good MP cannot grasp what it is like to have to live on a smaller income. To be a good MP you have to spend much of your time thinking yourself into other people’s situations, to decide whether and how government can help them. All sensible MPs want their constituents to be better off, and understand that if you have more income you have more choices.
