You wrote, "In actuality, it supports a red hot publishing trade that sucks millions of dollars from the pockets of college students who only want to learn the truth of things." Yeah, better be on guard against those greedy textbook publishers who supply schoolbooks to everyone from kindergarten through graduate school.
Yes, dead serious.
Until retirement, I worked in the employment of a local State College in the computer department. Private conversations with instructors in other disciplines illuminated me as to the severity of the problem.
Do you work for a college? Are you unaware of the problem? If you don't believe me, then go to your own local college and interview several instructors for yourself. You will learn the same things I relate here. Google the subject.....PLEASE.
Textbook publishers deliberately alter the layout of textbooks. Sometimes its as simple as shifting chapters around. For instance, in one year chapter 6 might come after chapter 5. The next year the information in chapter six might appear after chapter 10. This prevents students from selling their old textbooks to new students so as to obtain money to defray textbook purchases for the next term (or to supply beer money).
In the same way, the internal subject matter and accompanying illustrations, are altered from year to year so as to promote sales of the new volume. In recent years, textbook sales have migrated to digital media which makes it nearly impossible to pass along the text to newer students or to even recover a modicum of the expense.
A chemistry professor once told me she believed the textbook publishers are attempting to rewrite the PERIODIC TABLE OF ELEMENTS. This sounded ludicrous to me, but she assured me they were serious about it.
So should you and anyone else be who reads this.
Check it out. THIS is one of the serious problems with higher education today. Student loans are particularly high because of practices like this.
Hope this helps.
that's me, hollering from the choir loft...
