If Dubai hadn't saved a buck when they built the runways too close together to allow true dual runway operations maybe there would have been no diversions, more than 4 departures an hour, no 90 minute holding, no holding at the FIR boundary, no 4 hour waits on the apron, no waiting on the ground at outstations, no 10s of thousands of people in the wrong place.
And it'll be the same tomorrow.
