I know this going to sound shocking but half of the population has below average intelligence (yeah, below mean, but shush:) I think what happens is that everybody needs to have a job and source of income and people try to do the best for themselves. But, of course, they don't get more intelligent. As the technology progresses, more and more jobs are high skill or abstract tasks and both require intelligence. What this means is decreasing availability of intelligent people for the jobs and necessary incompetence of people who perform them (or the positions would not be filled).
