And designers, inventors, innovators are not pixies. They are the ones who add the value. It should tell you something that these jobs can be performed by incredibly low-skilled people overseas.

BTW, you seem to be making a case for college by citing a "dumb workforce." In fact, American workforce is getting much more educated---as it always has been throughout our history.

Manufacturing, IT, Financial, Medical, all those careers are being gutted by overseas resources and foreigners brought in.
