According to reports there is little social mobility amongst the professions
Politicians, media and the law seem dominated by public schools and Oxbridge. Just look at MPs, particularly the cabinet.
I work in construction where there are very few from this background. Anecdotally its one of the few places for those with criminal records. There are plenty of politicians who should have a criminal record but those who set the laws seem able to break them. Imagine if anyone else could simply pay the money back when caught, prisons would be nearly empty.
