If nothing taller than the Sears Tower were built in Chicago, would it matter?

I realize that it was nice to have the world's tallest building in our city, but in reality, does Chicago absolutely have to have that title again? If many new tall buildings are built, yet none of them taller than the Sears Tower, will it make a big difference? If the Central Area Plan comes into fruition, transit is improved, and the population continues to slowly rise, what more will Chicago really need?>
