The Industrial Revolution is usually cited as the point at which this Middle Class started to grow, and become much more influential. At some point during the 20th Century, it became quite clear that these three strata were inadequate to describe all the different echelons of society, particularly as very wealthy businessmen were emerging from "middle class" backgrounds, but couldn't be described as "upper class" because they had worked for their fortune.

Sorry Ralph, but I have to pick you up on that.
The whole reason for England's obsession with class is that England more-or-less invented the whole concept and did so WAY before anyone else followed on. The Industrial Revolution was something that happened at different times in different places. It happened first in England (mid-18th century) largely because a substantial, wealthy, well-established Middle Class had already existed for well over a century by then, and had pretty much taken over running the country in the mid-17th century by winning a Civil War against the aristocracy.
By the mid-19th century, when England's innovation was being actively copied across Europe and others were having their own Industrial Revolutions, the Middle Class in Spain, France and Germany was relatively small and politically weak. The appalling destruction of the wars of the 20th century also destroyed any chance of class becoming an obsession in those countries.
Meanwhile in England the class structure which had emerged in the 1640s sailed sublimely on, virtually untouched by three centuries of upheaval and becoming progressively more and more ingrained.
