Your argument sounds like a bunch of pretty arrogant generalizations to me.
I think I see what you're trying to get at, but regardless of its basis in fact, the ad hominem tangent in the third to last paragraph really derails and cheapens the argument.
Anyone who thinks developers are sheep that can be fleeced behind the barn is invited to try it.
Sheep or not, any dollar that developers earn above the government-mandated minimum wage is due to the free market forces.
