"63% of jobs in America will require a post-secondary degree by 2018."
This statistic comes from a report by the Georgetown Center on Education and the Workforce, which also stresses that the disparity in earnings is now at its greatest between high school dropouts and people with professional degrees (accounting for a difference in earnings of $3,452,000 over an entire lifetime). Having any post-secondary school at all, even without graduating, is worth an extra $473,000.
