Why have we become such an extremely stupid nation?
We haven't.
The measuring tools have simply become stupid.
Continually comparing apples to oranges.
People aren't stupid.
At worst they are over specialized.
Not only specialized, but specialized following utilitarianism.
Why do you think "pursuit of happiness" is in the declaration of independence.
Not too long before that "happiness" wasn't the be all end all of human civilization and individual living.
It used to be tempered by different religious dogma and its push for moderation.
You can't identify american values without spotting christian religious influence, but you can't do it without spotting utilitarianism either.
P♦eople pursue what makes them happy.
If it doesn't make them happy then it's "bad."
Ask any mother what she wants for her children "I just want them to be happy!" or what's she's told her children to do "you can do anything, but pursue what makes you happy!"
That doesn't make people stupid.
Just extremely smart towards making themselves feel good and really smart in avoiding anything that makes them feel bad.
Really smart along the path they believe will lead to their happiness, and smart along the path they believe will lead to the least amount of harm (which may influence their finding "happiness").
But that detracts from training and learning where they need to delay happy gratification, detracts from civil responsibility, detracts from things like honor, and duty, and civic obedience, and civilization, and social stability, and getting along with others, and being "well rounded."
People aren't stupid, they've just been trained where to apply their intelligence.
And it is not in areas that are all that conducive to group/family/national unity, social stability, or in a whole bunch of different areas that may help other people more than themselves and their emotional gratification.
The "American dream" is ultimately the individual achieving their highest potential.
When you train people to believe their highest potential is in making themselves "happy," that's where their intelligence is going to be focused.
Everything else is just trying to learn a way to get the resources to achieve that happy high.
American people aren't stupid. At best we're an experiment of the utilitarian ideal.
Our priorities are simply different than other cultures and nations.
Measuring as though everyone wants and values the same thing is stupid.
No different than comparing an Amish kid to an Apple iPhone fanboy and saying the Amish kid is "stupid" because he can't figure out how to download the spotify app faster than the fanboy.
What's stupid is to compare them to each other in the first place.
