What is the point of parliament?

Vince Cable is caught expressing his view that the Rupert Murdoch empire is more than big enough & he, Vince, is prepared to take it on. He is immediately stripped of the task of deciding if that Empire can be allowed to get bigger. The decision is given to Jeremy Hunt who had already expressed the view that allowing Murdoch to have the rest of BSkyB would not make a substantial difference to the plurality of the British Media. So disagree with Murdoch & be relieved of your duties. Agree and be given them. How impartial, especially when David Cameron & James Murdoch were apparently guests of Rebekah Brooks - Murdochs right hand woman - at Christmas. And the Government allows the Banks to carry on unpunished whilst the rest of us pay for the greed & stupidity of people who think that their 'talent' deserves obscene reward & we should stop bashing them [Davos]. Why don't we just shut down parliament & recognise that we will continue to be dumped on by the rich & powerful & save ourselves the expense of politicians.
