Intelligence gives you means to do something and Wisdom gives you means to know what ought to be done. Thing is, the higher your intelligence, more capable you are at self-deception. Being very intelligent is very advantageous in solving difficult technical problems, but intelligence is not sufficient to determine which problems to solve.
I'm pretty intelligent. While I don't have problems with determining which problems to solve, I do tell people that what I am good at, I'm up there with the best. My hyper analytic nature has worked great for me. But some things I'm not good at all with. The wife has to point me in the right direction in the morning. I have to not "talk shop" with normal people. My memory is a huge problem for most people, so I let them lie to me. Hint, calling out people every time they lie is difficult. Most people lie constantly.
But all of this is something that can be adapted to get by in life.
I had a friend who was operating on yet another level. A professor of acoustics, most considered him "Einstein level". and one of the nicest people you'd ever want to meet - when he retired it was a mega tear fest for the staff assistants.
Couldn't figure out things like how to dress or put a view foil on the projector the right way. His wife ended up fixing the dress problem. She bought him 5 identical suits, ties, shirts, and shoes. A different group for each day of the week. He could grok the logic in that, so just put on the group she laid out for him in the morning.
We can (and should) import highly intelligent people from other countries, but they won't have a reason to come to US unless we also have wisdom to have a good country to live in. This is exemplified by China - a country of highly intelligent and orderly people that lack wisdom to build society that anyone wants to live in. This could also be us if we fail to understand what matters - personal freedom tempered by person responsibility, self-determination, freedom of speech, equality under the law, and opportunity.
The US has long had highly intelligent people come here. It has worked to our advantage. There is a reason many do not wish to go back to their country of origin, as you note. As for the situation you allude to - this too will pass.
Intelligence alone won't get us anywhere, or China and Israel would be the best places to live.
Exactly. While the propagandists some of the media, and insecure would have the world believe else wise, the USA is a pretty good place to live.
