they don't manage 50k people any more than a nurse does or a social worker. They're not worth anything like 100k a year either, IMO. for dealing with constituents, maybe 30 k max. For turning up and voting as directed by their party - about - 5k. So that's 25 grand a year value they give. Now if they were more independent of mind, voted with their true beliefs, thought for the benefit of the people they represent, not the party, then their current wages are about right. As for a payrise, not until they demonstrably prove they deserve one. No other line of public work will get 11 percent. Paying them more will not make them better.
In fairness you need to pay for quality, but then the amount of Unite drongos that are bring fast tracked for Labour nominations suggests that quality is in short supply.
Out of curiosity, why would you turn that into an anti Labour point?
