<p>Also, when tenure track faculty in engineering and some sciences are hired, they have HUGE start-up packages (research money to set up a lab, computer equipment, etc.). In the university where I work the start-up package for the natural and physical sciences/engineering were six number figures, mine in a social sciences department was less than 2000 (mainly office furniture and a computer), and a friend in the English department got about 1000. The $$ for that, the newer buildings (engineering and sciences are always in newer buidlings), etc. might explain the tuition differences.</p>
<p>BTW, the provost confided to me that still, humanities and social science majors still partly subsidize the sciences (it is way cheaper to find 1 person to teach the same 4 sections of Enlgish 101).</p>
