The emergence of a half dozen leaders in education provided the personal force that was needed. Moreover, an outcry for a fresher, more practical, and more advanced kind of instruction arose among the alumni and friends of nearly all of the old colleges and grew into a movement that overrode all conservative opposition. The aggressive ’Young Yale’ movement appeared, demanding partial alumni control, a more liberal spirit, and a broader course of study. The graduates of Harvard College simultaneously rallied to relieve the college’s poverty and demand new enterprise. Education was pushing toward higher standards in the East by throwing off church leadership everywhere, and in the West by finding a wider range of studies and a new sense of public duty.

As a result, they are employed doing jobs that afford them little or no satisfaction. Our school leavers face so much competition that they seldom care what they do as long as they can earn a living. Some stay long at a job and learn to like it; others quit from one to another looking for something to suit them. The young graduates who leave the university look for jobs that offer a salary up to their expectation.
