Journalists report complaints that, "these days, if a student is lucky enough to study in the West, he will rarely come home. There are so few good jobs that everyone, from students to middle-aged engineers, is looking for a way out." An estimated "two to four million entrepreneurs, professionals, technicians, and skilled craftspeople (and their capital)" emigrated to other countries following the revolution. This flight of intellectual capital is estimated to have cost Iran $80–120 billion, where even the lower figures are greater than Iran's total oil revenues for 1989–1993.
