The time put in by a professor is actually pretty significant.
If I were to break down my wife's time into hourly wage, she'd only be making about $15 to $20 per hour. She spends godawful amounts of time in meetings, with students, grading, preparing lectures and so on. I would guess that she typically puts in about 60 to 80 hours per week.

They have to pay a flat amount for a class taught over the summer. As the guys making $150K and up would find it insulting to work for the same amount as the guys making only about $40K, they base it on percentage of annual salary. To an academic these sorts of politics are IMPORTANT, as they deserve some RESPECT for their position.

Me, I think they should pay a flat fee to all of them, prides be damned. But hey, what do I know? I'm just an engineer.
