Actually, I would say your argument would be like saying a line worker who installs doors on Hummers should make more money per hour than one who installs doors on Cobalts, because GM makes more money off of Hummers therefore the one putting doors on Hummers creates more revenue for GM

. Doesn't make sense, does it?
No it doesn't make sense, because you don't understand what I'm saying. What I'm saying is a worker who puts 6 doors/hr on a Cobalt (6 UNITS) should make the same as a worker who puts 6 doors/hr on a Hummer (6 Units) 6 units of work is 6 units of work. It's the same job.
I don't know what you fly, but I'll pretend it's not a 747 or 380. We'll fly from, oh, IND-MCO. About 1000 nm. We'll say you fly a CRJ with 50 seats, and I'll fly my 747 with 500 seats. Now, Doug in his 300 seat 767 flies the route too. You'll make 50,000 ASM (...or 50,000 units.) Doug will make 300,000 ASM (or 300,000 Units), and I'll make 500,000 ASM (500,000 units). Who generated the most units? Me.
Now, you fly your CRJ with 50 seats, and my buddy from the old shop will fly the 50 ERJ. You generate 50,000 ASM (50,000 units) and he will generate 50,000 ASM (50,000 units).
The CRJ and ERJ produce the exact same number of units, just like the guys installing doors can only install 6 doors an hour in either place.
The other comparison shows that the larger aircraft generate far more units than a smaller aircraft.
