Create cover for book on college majors, as a warning to avoid costly impractical majors

Duard G. Slattery, Jr.

This is a guide book on college majors, with emphasis on Return on Investment (ROI) of each major. Clear warnings are given, for those majors that are a poor investment.
Target audience is American students, parents, teachers, businesses and government, in fact most of American society, anyone concerned with a trillion-dollar student debt!

This is a book of guiding information on college majors, but also a book of WARNINGS! Clear warnings are given for those majors with poor Return on Investment (ROI). In the text, the RED FLAG is used as the symbol of warning. So you might want to design a cover around a RED FLAG of warning.

Some ideas and symbols you might want to use:
• Trying to stop a speeding train, by waving a red flag?
• College is a train, speeding toward a cliff?
• College is a train, on train tracks that go nowhere, into the weeds.
• College is a train, headed for a train wreck.
• Huge mob of students, all in caps and gowns, rushing over a cliff, like lemmings
• Simple Cap on white background, like cover of William Bennet book, “Is College Worth It?”
• Close-up photo of young graduate face, under the square cap, looking dead-serious
• Graduates in cap and gown, in unemployment line
• Graduate in cap and gown, working at coffee shop
• Graduate in cap and gown, driving taxi
• City scene, with dozens of manual laborers, taxi drivers, etc, all wearing caps and gowns

Sending me some simple sketches early would be good, so I can give early feedback.
