The MIC and the NDEA is one of your abiding concerns, and it isn't altogether misplaced. However... The NDEA did have some democratizing effects by enabling people to attend college who otherwise would not have been able to afford tuition, housing, and books. My siblings were beneficiaries of NDEA grants, as were many of my fellow students. Me too. All that was back in the late 1950s and mid sixties.
Don't overlook the insidious effects of VA education benefits that sent many, many former soldiers from WWII (and later) to college.
I quite agree that the Military Industrial Complex (MIC) was. is, and probably will remain alive and well. I would like to quarrel with your chronology and widen your target aperture.
In focusing on the post WWII MIC, you are overlooking some other malignant influences: Don't forget about rampant capitalism: exploitative, often ruthless, anti-union, and focused on necessary (from their perspective) class warfare (which is what their anti-unionism is about, among other things). The manipulation of the public got a big boost in the work of Edward Bernays (1891-1955) the 'father of public relations'. Bernays was the nephew of Sigmund Freud.
The "bigger half" of the MIC is big business, the globe-circling ouroboros, infinite tail-swallowing snake. When a handful of capitalists (literally, less than 11) hold more wealth than 1/2 of the global population, you are dealing with something pretty powerful. Not to mention there are another couple thousand inordinately wealthy individuals out there, protecting their interests.
But getting back to the NDEA: Wasn't one of the benefits of the NDEA and VA education benefits a tidal wave of students (and income) that lifted all university departmental boats? Were not the humanities and/or liberal arts departments in much better shape after WWII on into the 1970s, then they later became (put on shorter rations at best)?
Another concern you have is
With the focus on technology came specialization and the Behaviorist Method of education which is also used for training dogs. — Athena
Sure, simple conditioning works better for training dogs than having long discussions with them. I've had long discussions with my very smart dog, and I can report that it didn't improve her behavior one wit (she was, of course, a very good dog).
It happens to be the case, like it or not, that human beings, dogs, monkeys, rats, and crows share many neurological characteristics. That's why we also learn in ways not much differently than other animals. Psychology's first big (and successful) project was to understand how we learn. So it is that the methods of the rat lab became the 'image of psychology'.
In saying that, please note, I am not equating a human mind with a dog's mind. The scope of human mental activities is far vaster than a dog's, and our brains are far more complex, and utilize additional methods of learning, knowledge acquisition, imagination, and so on and so forth.
Hey, Athena: I think we share a lot of discomfort, dissatisfaction, and disagreement with the world as it has been made. My disagreement here is that there are just more villains than the Military Industrial Complex.
