The sad fact is that America is no longer a country that makes things, and as a result we no longer find ourselves in a position to employ people in positions that are actually worth a damn. Or that pay a salary worth a damn.
We still make some things. Software. Circuit designs. Entertainment. Product design (to sell things to ourselves). Pharma. People who work in these areas are paid well.
Oh, and the financial industry. Which, despite demonstrating a wonderful ability to make itself mountains of cash, has failed to demonstrate how it benefits the rest of the country. (obviously, its ability to provide lines of credit is valuable, but we had that long before investment banking came to dominate the entire financial industry)
I remember reading Snow Crash for the first time and coming across this line:
There's only four things we do better than anyone else:
music
movies
microcode (software)
high-speed pizza delivery
and thinking "what an alien dystopia that future must be".
