You're absolutely right about those pursuing their own ends. They're supposed to be representing the views of their constituents but far too many of then seem to think that they've been elected to vote for "what they think is good for them".

Theresa May is in an impossible position, whichever way she turns she's in a no-win situation.

You're also right about some of those in Parliament who have only followed th course of School, College, University" and have never held any sort of responsible job and think that they "know it all". As with local Councillors, it should be a condition of application that they've made some sort of impact in a "proper" job before being allowed to enter the Political heirarchy.
