This drives me nuts. The REAL reason the elites put up with vulgarity, poor language and reading skills, poor math skills, and other things - like slovenliness, early unwed childbirthing, and consumption of undocumented chemicals, is because they think "those people" - the lesser classes - are incapable of change.
In other words, they think the lower classes are just stupid.
I just can't understand why the average American doesn't call the Elite out on that. They put up no fuss when the academic requirements for occupations can't be met without post-high school education, which is both expensive, and, increasingly, not worth it.
