Well, there's a little throwback!
What the old "Dodgy Geezer" seems to be advocating is that if an MP is unpaid for his/her/its services (apart from expenses of course), then only those with mega-bucks in their back pockets would be able to become an MP. So back to the days of the "Rotten Boroughs".
OK, I'll accept that the annointed plebs have proven themselves just as corrupt as their wealthier counterparts, but surely simple lack of wealth (be it Land, Cash or Influence) shouldn't be a barrier to becoming an MP. So, to my mind, "unpaid" MPs is a non starter.
For a start, why do people wish to become an MP? (NOT a Military Policeman). Ego is my answer to that. They may all spout platitudes about wanting to help "their fellow man"...but in reality, all they wish to do is to exercise control over them.
My previous post about the poor sod who got executed has another reasoning behind it......never trust a person who puts himself/herself up for an election into a Public position. BY.
