"but not smart enough to figure out they are being used" As if, if they were smart enough, they would do...what? The implication is that you can't have a stable situation in which people are being "used" with their knowledge. That doesn't make sense to me. My perception is that what keeps the system stable is that different classes of people have different value systems, and they accordingly dehumanize other types, which keeps them from encroaching on others' territory.
