Not only can Liberals form them with (re)education. They can also enslave them with debt.
And, interestingly enough, Obama made that indebtedness direct to the government, not indirectly to a bank holding a federal guaranteed student loan.
Once indebted, many will feel helpless, and feel that they have to vote for government benefits (like debt forgiveness). These people are directly indebted to the government (not to banks thanks to Obama), so they can be controlled (that is, they feel like they are voting for people who control their indebtedness, and therefore they are more likely to vote for the party which is most likely to forgive their debt). It is a direct form of political control in a democratic republic. Lots of things wrong with our current system.
