The problem with society is that people are willing to sacrifice the good of others in order to gain something for themselves. They also tend to lie to themselves and/or are oblivious to it. The problem is within us; better intelligence will just let us do it with more sophistication, or perhaps on a larger scale. One of the main force within society pushing against having all our arrows point inwards is religion, which these days isn't even in consideration for membership in the set of useful things.
