Yeah, sure, we're near full employment economy and PhD's can't find any work. B.S.
You certainly are not good at math if you confuse the overall employment rate with an industry-specific one.
Does this survey:
http://www.ams.org/notices/200507/survey.pdf
support your assertion that "US DOESN'T GRADUATE ENOUGH MATH AND SCIENCE STUDENTS"?
Did you want to set up a government program guaranteeing everyone with a PhD continuous employment at the salary of their choosing?
The survey you posted only shows the number of PhD's earned, not MS or BS degrees. So it's not really indicative of the number of students graduating with math, science, and engineering degress. Furthermore, since 1999 half of the PhD's earned in the U.S. - according to the survey - were by foreign students. I would say this is proof that we aren't educating enough of our own students in this areas if we are filling our universities with foreign students. So the answer to your question is yes - the survey supports the view that we are not graduating enough math and science students.
