Take a chill pill West Coast. I think you may have misunderstood and gone on the defensive. I think ATC in the USA is some of the best in the world. What I wrote are generalizations of my own observations from personal experience and the witnessing of a few "close calls" over many years working in ATC. I'm not aware that I said this was the cause for the MDW incident. When I said, " some contributing factors are possibly" I was referring to my first line and not specifically to the MDW incident. But on reflection I can now see that I should have made that somewhat clearer. Oh, and note the word "possibly".
