The trouble with the "not allowed any outside income" is you end up with solely professional politicians.........which is part of the problem anyway and also a lot of those with real world experienced and talent like businessmen people, lawyers, doctors etc. would probably not bother for that income on those hours for what could be a very short term, not guaranteed job.
We need more of these people in politics not less. The problem in politics is not the "outside income" it is what the people in there do while they are in there! i.e. make policy to help mates (or themselves) or cronies or end up just being part of the carousel of buzzword sloganeering. A vast amount of what we see and hear from that place i pure and simple worthless.
PMQs is the biggest waste of time going but the bubble warble on as if it matters at all. It is, and has been for eons, the government's folks standing up to say would the PM agree that we're doing really good stuffs, to which of course he does and any questions presented to the PM are not answered Whoever is PM just fires a question back instead.
So I disagree about the no inside income. We would just end up with people more isolated from the real world than we do now..........or a load of Trumps that sign off their outside interests to someone special ready to pick it up when they exit.
Its just a matter of making sure those people whose talents have been brought into the house "play by the rules" AND by the spirit of the rules. We barely get the former atm and none of the latter.
