Jess Phillips spoke sense on the earnings vs skilled/unskilled - the speech mentioned by ma non troppo.
The oft-quoted highlight:
Perversely, since I was elected I have met many people who earn way more than £30,000 and have literally no discernible skills, not even one. I met none before—I thought I had met posh people before I came here, but I had actually just met people who eat olives. I had no idea of how posh a person could be. Waitrose is apparently not the marker for being really, really posh. There is a lovely Waitrose in Birmingham Hall Green; it is the one I like to frequent. I have not necessarily met such people in this place, although there is a smattering. I would not let some of those very rich people who earn huge amounts of money hold my pint if I had to go and vote while in the bar, because they would almost certainly do it wrong.
