Many of the textbook companies are linked directly to Wall Street. McGraw-Hill, the largest, is Standard & Poor's. J D Power & Associates, and Platt's, among others. This is from their website:
Overview
The McGraw-Hill Companies is driving the financial services, education and business information markets through leading brands such as Standard & Poor's, McGraw-Hill Education and J.D. Power and Associates.
McGraw-Hill aligns with three enduring global needs:
* the need for Capital
* the need for Knowledge
* the need for Transparency
These are the foundations necessary to foster economic growth and to allow individuals, markets and societies to reach their full potential.
The reason they avoid or obscure labor history is that they cannot possibly do the subject justice without revealing just how mercilessly destructive capitalism is, which, as we see above, is not in their interests. The government, media and school system is there for management perception. Capitalism couldn't survive a day if the truth were told.
