Should we discourage students from investing in a liberal arts education?

Essay Prompt
As the economy begins to rebound and people continue to search for jobs, much attention has been paid to the kind of college education students obtain. In particular, the argument has been made that students should focus on STEM fields rather than on the liberal arts and that the liberal arts are, if not useless, a poor investment both for individual students and for society as a whole.
In a 6 to 7-page essay, respond to that argument. Should we discourage students from investing in a liberal arts education?
