Given there are only two major institutions that are capable of winning under the current rules, one of the two institutions figured out it's advantageous not to have highly educated constituents.
Over the period of about two generations they've managed to rig it so that only the upper class can manage to get a fair education. So the poor malleable people will vote for whoever they're told to vote for, and the ultra-rich will vote for the side that is most advantageous to them.
In a time where we should be trying to get as much education into every living being that we can, degenerates are using a lack of education as a wedge to stay in power.
