s-freak, I'm not sure why you're so obsessed with the total amount of money spent on R&D. If the analysis were really that simple, we could have had Topspin report to congress, instead of having a highly respected, Bipartisan Commission and their professional staff study this for months.
For one thing, "total" spending may not tell us much. I bet the United States government invests most of its R & D money into weapons systems, Star Wars missles, and the military industrial complex. Not into basic scientific research and eduction that better utilizes human capital and promotes sustainable economic and technological growth.
Second, I already pointed out that lumping together private research, with publically funded basic scientific research, is to lump together apples and oranges. Proprietary applied research is aimed at immediate consumer benefits, and have demonstrable profit motives. And, importantly, its proprietary -- i.e., its not shared knowledge within the broader scientific community.
Secondly, investment into human capital, basic research, and education have to be broken apart an analyzed. Are we keeping up with other countries in how we manage, distribute, and invest our public resources to best promote human capital and keep our scientific edge?
There are a host of issues that have to be analyzed, rather than just looking at who "spends the most, overall".
Now, if you think Topspin came up with the right answer, after he thought about the issue for five second (i.e., "Were the king! There's NOTHING to worry about!"), then fine.
As for me? I'm going with the analysis and conclusions that an entire Bipartisan Commission of prominent Republicans, Democrats, and their professional staff, who took months to analyze and come up with: We're facing a problem, and in danger of losing our edge to competing nations.
