^^^ What do you mean by that? Chicago still has tons of ornate neo-classical buildings left and none of those give a big old "fuck you" to pedestrians like the Federal Building did. For example, the Jeweler's building which puts the old Federal Building to shame:

(Note: Jewelers Building is still standing and is not in threat of demolition)
My point about the old Federal building is not that its inherently ugly (though in my personal opinion it is) but that it is culturally and architecturally insignificant and contributed nothing to our city's history. The Mies buildings, on the other hand, are masterpieces that have actually contributed to the history of Chicago architecture.
