I think you are being too absolute.
There is some value to the content, even though I totally agree that the contacts are dramatically more valuable than the content if you go to a good school.
Personally, I find that finding management and business content on my own is actually harder than finding Engineering content on my own; management and business training is full of tony robins style confidence men, and it's difficult, for me at least, to sort out what is actually worthwhile. For that matter, just an overview of what sort of professional to hire in what situation would be nice. (For instance, if you are just looking for tax help and don't plan on selling the company, an 'Enrolled Agent' is actually better than a 'CPA' though the two certifications are of similar difficulty; the EA focuses on dealing with the IRS, while the CPA has more of a focus on the accounting you would need if you are selling your company or something.)
