The above link is a superb (and large) picture of Trump Tower Chicago from the top, with a full aerial view of the spire.
It perfectly illustrates what a joke this particular spire is. It looks like a PVC pipe held up by a couple of wires, and looks as if it can break off any second from high winds. The glass curtain around it is there to hide that atrocity, but from the ground it appears to be structural or even another couple of floors - another joke.
See for yourself.
