Guess what? Pretty soon the wage that goes to the engineer that INNOVATED the protection is going to be going to China too unless this country wakes up and starts generating some scientists and engineers! THEN we'll be in a world of shit. The world is flat.
I agree with your warning that the tech jobs will soon follow the manufacturing jobs. But if you're saying that technology jobs are going to China because there aren't enough sci/engineers here to fill them, then I strongly disagree. There are too many well paid US scientists losing their careers here because jobs are being outsourced TO SAVE MONEY. (And don't respond with some academician's essay about the shortage of technical graduates. US universities have been banging that drum since the Kennedy administration. It's called job security.) Let's find professional employment figures for the traditional American powerhouse industries: oil, steel, chemicals, technology. These industries are in full flight out of the US. Hell, even the entertainment industry seems to be globalized now. Hollywood? Where's that?
Yes, the world is flat. And small. And the US is an economic dinosaur.
