"...would it not be a good plan for all future Tory MPs to serve a term of say 5 years doing a proper job & finding out how the majority of people have to live to make ends meet ?"
You must mean the sort of "proper" jobs that this lot have held, Ron:
Jeremy Corbyn (brief career as a junior reporter on a local rag, then full time trade union representative before entering politics)
John McDonnell (Researcher for the NUM and the TUC before election to the GLC)
Angela Eagle (Briefly worked for the CBI before working for the COHSE health union and then on to politics)
Lillian Smith (Various work for the trade union UNISON before politics)
Heidi Alexander (Researcher for Joan Ruddock MP and then Campaigns Manager for Clothes Aid)
Dianne Abbott (Two Years as an administration trainee at the Home Office then on to the National Council for Civil Liberties before politics)
Hilary Benn (Worked as a research officer for two Trade Unions before politics)
Andy Burnham (Researcher for Tessa Jowell, parliamentary officer for the NHS Confederation before politics)
Just a few of the members of the current Shadow Cabinet taken at random. I’m sure I could find a lot more if I tried. Is it “pots and kettles” that spring to mind or is “Let he who is without sin cast the first stone” more appropriate?
