You all are missing the purpose of the article. It is not to bash higher education or other things, it is to direct the people to focus on sales.
You all are missing the key sentence in paragraph 13.
"Rather than acquiring secular degrees and titles after their names, true Christians focus on obtaining “letters of recommendation” by engaging as fully as possible in the field ministry"
That is what it is all about, bullying and goading them into more field ministry. So that the readers can use their cars and gas and time to deliver the WTS literature to keep them busy and engaged and active and then to bring in more "customers" into the organization. Just admit it. The term used is sheep but really they are customers paying the bills.
