For many young Americans, deciding on college has become a complex choice. Increasingly, a main question is whether a degree is worth its cost. Confidence in higher education has dropped due to high tuition, student loans and a tough job market. Colleges are now trying to prove their value. New rankings and reports focus on the financial benefits of degrees. Research shows most bachelor's degrees still pay off, but not all lead to good salaries. More students are choosing technical schools or trades over four-year universities to avoid debt. In response, colleges are working to align degrees with job market needs.
