The negative stance against higher education is a smokescreen.
They reason that a young (innocent, vulnerable, simple) person will be exposed to immorality, drug and alcohol abuse, politics, evolution and higher criticism.
In actuality, the GB doesn't want people to become educated. Essential parts of a successful education are to learn to reason, question and prove.
And the local elders DO NOT want publishers that are 'smarter' than they are. Register for a four year college or university and see how quickly extra 'privileges' are taken away!
