Copy? Desperation move? If you want to get technical, DFW looks alot like Atlanta you know. Did DFW copy ATL? What about LAX, they use 4 parallels too? And of course congestion will be lower when the volume at DFW is less than ORD, and I would imagine the weather tends to be better as well. I agree that ORD, needs to be reconfigured, but I would'nt call anything a copy.

Not a copy at all. Just logical design.
Old airports like ORD evolved from grass strips which, for the light aircraft they accomodated, had runways aligned with prevailing winds. Today, all the new airports use parallel runway sets, and many of the older airports are slowly replacing their crossing runways with additional parallels.
Probably some brainiac did a complex computer model to show ATC can move more traffic more efficiently this way? The same brainiac also discovered that sewers function better if they flow down not up...and round wheels work better than square wheels. Gotta love technology!
