I'm not sure I would take dailykos as gospel, any more than redstate.org.
I think every generation has thought the next generation was inferior. In fact, I think in every country there has been a small portion of the population that became engineers and scientists. You can find bumpkins in America, but you can find people in Germany or France who are anti-semetic and superstitious too.
Having worked in industrial research, let me also say that America is still the origin of most fundamentally new innovation. Certainly far more than Asia and more than Europe, despite its population and fine educational system. There are just certain cultures that produce good rock music, good programmers, and good inventors. These seem to be Britain and America, for reasons I can only speculate on.
If China becomes the leader in the space race, it would only be by copying someone else. My policially incorrect observation has been that their scientists work hard but do not think out of the box, ever. And in their extremely hierarchical society, it is not unusual for someone politically skilled but not technically competant to rise in organizations, and no one below him can question or subvert any bad decision me makes.
Having said all that, I still wish there was more emphasis on science and engineering in American education. The lore has always been that America produces incompetant 18 year olds, and brilliant 30 year olds. Our high schools suck, but people still come here form all over the world to attend our best universities and institutes of technology, or to work in our industrial research labs.
America is also, unlike Europe, a fairly classless culture. You don't get shunted into a trade school at age 14 or 16 if you don't pass the right test or come from the right family. Take for example John Carmack, the author of DOOM and Quake games. His work was technically very original, and he has only a high-school education. Our free-market culture allowed someone, with no credentials or hereditary-class advantage, to have a good idea and make it happen. That is very difficult in other cultures. For that matter, the very idea of the internet and personal computer come out of that culture. So what we lack in uniform educational quality we make up for in opportunity.
