Somehow, I don't think this could have been their lifestyle 200 years ago. Before the mid-20th Century, everybody's situation, of whatever religion, was "work or starve" (unless you had inherited a lot of assets).
It was, but the pyramid has flattened.
There always was a scholar class supported by the rest, but over time the membership in that class seems to have expanded to embrace a larger and larger portion of the population.
