Unequivocally No.
If there was too much of a focus on STEM, there would be an oversupply of scientists, engineers, and technicians in the economy.
In the United States, we all know the opposite to be true.
I’ve also witnessed many times those who lament the multitude of Americans who don’t know the difference between Monet and Manet, but then get hostile when you ask them a basic question about math or science.
But even more important than this, is the need to eradicate the anti-intellectual, anti-knowledge, anti-thinking undercurrents in society. When those who are highly educated and experts in a field are viewed negatively as elitists, there is a major problem. When people believe the that all opinions are equal (for example, when a pundit believes they are just as knowledgeable about a subject as an actual expert), there is a major problem. When people willingly disregard facts, logic, and rational thinking because they “believe” something different, there is a serious problem. When people dislike President Obama because he uses “big words” and “speaks above an 8th grade level”, there is a serious problem.
There is nothing intrinsically elitist about someone who is more knowledgeable than you are in a specific field. I will never claim that because I played golf a few times I’m as equally qualified as Tiger Woods to talk about it. I will never claim that because I wrote a few school papers on the American Revolution that I’m as equally qualified as historian David McCullough to discuss it. I will never claim that because I took a marco-economics course that I’m as equally qualified as Economics Noble Prize winner Paul Krugman to determine what’s best for the economy.
