Why the British Public has given up on Politics

Several thousand young people in the north of England are groomed and sexually abused, hundreds if not thousands of people are being butchered by IS and other groups in the Middle East and Africa, Tony Blair pockets millions from consultancy work purely as a result of being prime minister (we won't mention Iraq), the Chilcott enquiry will report sometime in the 22 Century.
Meanwhile our MPs waste thousands of hours and probably millions of pounds om worrying about three stupid schoolgirls who went to join IS. Where is the sense of priorities and a sense of scale?
