One thing that have been thinking about recently regarding the WTS's position on "higher education" is that it helps them weed out the people with a Rebellious Spirit™, and reward people who obediently follow the WTS's directives by doling out Privileges™ to them, while withholding Privileges™ from others who disregard the Suggestions™ from the Organization™. It is about CONTROL, more than anything, and finding out who is willing to subjugate themselves to the Organization™'s directives and who is not.
that could be, but in my area I can name at least 5 young elders under 30 years old who have an education and only 1 young elder under 30 without an education. very limited sample, I realize, but it doesn't seem to hold the brothers back. I'm not so sure about the sisters, though.
