Comparing total passengers and total crew for different aircraft doesn't work when you have different numbers of classes and different numbers in each class.
The best comparison that highlights the difference is looking at J class on an A380 and a 744P.
A380 8 crew for 72 J class 1:9
744P 6 crew for 66 J class 1:11
As I said in a different thread, they could easily lose a crew member in J on the A380, but unfortunately the crew are not experienced enough to get the job done in reasonable time with 8, and as PattyStacker said, the crew are cheaper on the A380 so it is not as big a saving to remove someone.
