I like the cut of your jib. I see the class system in much the same way but with different analogies. The middle class professionals are like the 'house n-gro' described by Malcolm X and the minimum wage workers are like the 'field n-gro' (not sure we can use that word even in academic discussions given where the UK free speech laws are going!).
There is also a lack of a respected teaching class. With the changes to universities and schools, there is no longer any respect for those with an education and able to teach.
