the problem with all these slightly punitive ideas (less money, little pension, halls of residence) is that it will disadvantage exactly the kind of candidate you want.
In my opinion, what makes a bad MP?
People of independent wealth, by and large, who have little or no appreciation of what it's like to live on a salary and rely on a pension.
People who are career politicians and spend their lives in Westminster.
People who use their position to further outside business interests and sit on multiple boards of directors etc.
People in it mainly for the power trip.
What does the HoC need in my opinion?
More people of moderate/ordinary wealth
More women and people with families
More former professionals with experience of living and working in the world before they entered Westminster
More people in it for altruistic reasons, not for the influence they can wield.
IMO, many of these very punitive changes would put off the type of people who SHOULD be entering politics, and leave the field clear for the type of people who SHOULDN'T. If you are a working professional, perhaps a head teacher or a family lawyer, with a family and a mortgage, you are simply not going to enter politics if it requires you to take a pay cut, give up your job (and the best earning years of your pension) in return for an uncertain pension pot, commute miles and miles at your own expense, and live in a tiny flat in Westminster away from your family.
I am not saying the current system is right, but punishing MPs too hard will only mean that only those of independent wealth, who don't need a realistic salary or a pension, will be able to enter which would be much worse for British politics than a few people claiming dubious coffee tables and bath plugs.
