There seem to be far fewer UK politicians who are there for genuine altruistic reasons. Maybe it was never so and ALL politicians are/were there for their own gain?
I think not. In the past there seemed to be far more politicians in positions of power because they genuinely thought they could help build a fairer and better world. These days the House of Commons seems filled with toffs who went to public schools, work in share dealing or the big banks, make a career (on the side) of politics because they may be able to modify policies to their personal gain. Sadly, I think this applies to politicians of all parties. It is dangerous to generalise I know. I hope that those to whom we grant power to create and modify our laws do so with care,humility and for good reasons. It would be a very sad day if we totally lost faith in our Parliament.
