It would seem prudent to separate the sectors where there is real need from where there is mere abuse, then, rather than simply opening up the spigot.
That's my main point. It is even more justified when you take into considerqation that roughly half of the graduate students in science and engineering are foreign students. It is in the U.S.'s best strategic interests to keep those graduates here rather then have them return to potentially rival countries with their newly gained expertise and leave the U.S. with a deficit in brain power.
