£67 k is great wage, especially when expenses etc go a long way to negate any tax paid. If an MP somehow thinks they need another job to make enough money to live then, as this salary is for full time work, they should certainly only receive pro rata part time money instead.
I can't see that it would put off many people who would make good MPs either. Too many MPs are parachuted into their roles (looking at the current government for this) as opposed to actually meriting their position. For many people classed as WC, my background, who have the skills needed to make a good MP but, too often, not the opportunity, £67 k could be seen as attainable. If the pay is raised to £150 k or some other ridiculous amount, it could even put them off because, again, this reinforces the impression that the government is for the privileged class as opposed to ordinary people, who are almost always often more talented, hard working and intelligent than most current incumbents.
Sorry about the garbled post. I know what I'm thinking but I mainly posted to start to roughly formulate it.
