We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
When people think of Maslow, they tend to remember two things: the notion of "self-actualization," and his hierarchy of motives.
Maslow made several mistakes (one being the assumption that everybody is just like him, and another being his relative discounting of unconscious motive), but what is most interesting is how some of his ideas became absorbed into the culture in distorted ways.
To what extent Maslow studied Nietzche I do not know, but his post-modern glorification of "self" owes plenty to Nietszche. In the brave new world, Self replaced God, and the value of "self-actualization" replaced - for some - sturdier old values such as duty, honor, perseverence, integrity, decency, and - yes - selflessness.
To what extent Maslow played a role in todays pop-culture "It's all about me" theme I can not say, but what I can say, from speaking with a great many people over the years, that the idea that the person must strive to become a heroic manifestation of his Self has led far more people onto the rocks of life than I can count. One reason is, of course, that nobody's "Self," however talented or untalented, is really all that great, and is packed with the flaws with which each of us stuggles daily.
Furthermore, the culture's version of Maslowism leads to much feeling of failure. After all, if I have not fulfilled my potential" or "become who my inner self really is" or "fully actualized my precious self," a person can feel like a failure in life, a certain narcissistic defeat. We all use our gifts as best we can, given our ambition, inspiration, and industriousness, but I view "sef-actualization" as a false idol.
Well, for what it's worth, as a high school student in the seventies we studied both Maslow and Nietzche in our 11th grade Ethics class. We were certainly excited to find there was a philosohical basis for natural teenage self-involvement! It made it all seem right and proper not to give a whit about anything other than ourselves.
So, in answer to your question, I suppose you could certainly argue Maslow indeed did have an impact on us at the time. And it endures too: my local library (Princeton NJ) carved virtues into the wall of the new building a couple of years back, and none of the words were "duty", "honor" or the like.
met Maslow's Hierarchy of Needs in the early 70's in a therapeutic community ( a drug program) in Newburgh, NY. Despite Mr. Maslow's wonderful intentions, most of the clients decided what they really needed was a bag of heroin.
Maslow disavowed much of what others did with his work. Towards the end, I believe he even disavowed his own work, realizing that self-actualiztion only works with already civilized humans.
The story I was told is that he started questioning his own works after working with actual real live criminals. He pretty much found that they steal, not because they need something, or are deprived, but because stealing is what they do.
When I was in college, I was lectured about the insight and importance of Maslow's hierarchy in classes of every description: English, anthropology, computer science.... And I laughed and parroted every it back every time. Reminded me of Scientology, with its hierarchy culminating the perfect inner Thetan, or whatever.
Maslow's teachings, as they were presented in my high school psychology class (I should have taken art...), place the self-actualizers (a small mimority) at the pinnacle of the pyramid, which smacks of the modern liberal's snide condescension towards the lower classes.
