Corbyn, McDonnell and Abbott? :shifty::smuggrin:
That is some list. And it isn't very big.
How many actual MP's can you name off the top of your head? The most genuine are more likely to be those lesser heard of. They're not in it for the prestige or the power - they want to make the country a better place. There will be differences in opinion of how that should be done but the ultimate aim is the same.
Even most of those that have become disillusioned with politics and feel it's been a waste of their time and have now looked at how to get personal gain from it often started out or genuine altruistic reasons.
Those with a big public profile or are in the upper echelons of power and thus well-known are far more likely to be in it for themselves. So those more likely to be self-serving are also the most likely people will have heard of. and by so doing the smaller group becomes representative of the whole.
As for Abbott's 'evil' plan to pay bobbies £50 a year. That was that she's shit at numbers. She never meant she/Labour intended to pay policemen that and you know it.
