All three of those people were Lawyers (Ivy League Lawyers, BTW) before they became politicians. Even though I am an Attorney, I do not consider being an Attorney to be a "real job."
A real job is where you get up at 5 AM and bust your butt working up a sweat and at the end of the day you have accomplished something more than just squeezing money from the "little people" who have busted their butts all day to feed their families and pay their taxes to support the likes of those guys you mentioned.
I doubt if any of them ever built a doorframe or washed dishes or painted a house or stocked a shelf or dug a ditch. I'm betting they all got through college on full scholarships and started earning 6 figures from the moment they got out of college.
I know several lawyers, and all of them think that they have real jobs.
