Also see the "S" of STEM. Many people going into science at the graduate level believe the hype that there is a huge shortage of scientists and that they'll have no trouble getting a tenure-track job in the end. This isn't the case. The system is set up to generate many more Ph.D's than faculty positions because grad students and postdocs are useful sources of labor for faculty. That doesn't mean that you shouldn't go into science (there are jobs in industry and government for example), but realize that getting a faculty job is statistically unlikely.
