onmyknees, I doubt that you will be surprised to learn that Ms Warren is a graduate in law and was once, sigh, a law professor at Harvard (where her husband is...a law professor)...years ago when I was in the Labour Party here in the UK 60% of the active members (the ones who attend meetings and get elected to various posts) were schoolteachers, 30% lawyers or solicitors (a curious distinction we have in the UK you dont have there) and the other 10% quite possibly workers. This is how our political systems seem to be evolving. Labour leader Ed Miliband is the son of a well-known but now dead Trotskyist Ralph Miliband, who once wrote a book trashing, yes you guessed it, the Labour Party (!). Ed -who did his, sigh, year at Harvard after reading PPE at Oxford (so it was economics not law)- worked in tv for a short while before writing speeches for Harriet Harman and making his way through Labour ranks-having entered several layers above everyone else, so I don't know if he has ever had a 'proper job'. He isn't fit to run the UK, that's basic.
But are you saying to Presidential candidates -You can't run America if you haven't run a business? Doesn't that narrow the field? I understand the fatigue with lawyers and teachers, but at some point feasible policies that make a positive difference should be considered. I can't see anyone on the horizon in either the USA or the UK who makes me feel confident about the future.
