The question is...if they are able to see this kind of stuff, why a lot or most seem not able to do something about it? Is it for lack of Sensing?
This is my guess on what accounts for failures. Insights don't easily "pan out" due to external resistance, internal inertia, and the time + energy cost of translating what you see in your mind to what others see with their eyes. Ne types good at grasping the internal properties and potential of objects aren't as good as Si types at evalauting how objects dynamically relate and adjust to their spatial environment. Ni types good at predicting how objects change across time aren't as good as Se types as perceiving the "imediate, static qualities of objects".

Do you think there's a solution? Realistically and not romantically, do you think there's a solution?
A two-step solution to combat ego and unhealthiness is 1) realize and accept one's strengths and weaknesses through contemplation and discussion with oneself and others around him/her; 2) develop humility and appreciation for others: each individual has his/her own gifts and growth edges that should be used and worked on.
