The tower and it's attitudes toward each other were a sign of how society had broken down and made the time ripe for the Dark One to return. And for all of their thinking they were better than everyone else they had to learn the truth to survive. Turning away Wilders meant possibly turning away a talent even if underdeveloped. The tower was stagnated, Egwene and Nynaeve came in the the right time to be able to upset the way things worked and make changes that would never have worked if the tower was already whole.
