If New York, during the outbound international rush is not busy, not complicated; then the question must be-why in the hell is European airspace that complicated? New York Approach controls 3 large hub airports, 6 or 7 large GA airports and numerous small fields, all with appoaches published and active. Europe is that complicated, by my observation, because controllers like it that way. The continuing impasse over creating a real EuroControl, that had maybe TWO ACCs for the "Continent" and several large "approach" controls like NY or SoCal has is silly. But that would put loads of ATCOs "on the street".
