The escalating high education cost

The escalating cost of higher education is causing many to question the value of continuing education beyond high school. The high costs of tuition, opportunity cost of choosing college over employment and the accumulation of thousands of dollars of debt make many wonder whether all these problems justify the investment. The risk is especially large for low-income families who have a difficult time making ends meet without the additional burden of college tuition and other fees.
there is evidence that the rate of return on investment is high enough to justify it in spite of costy college degree. College graduates earn more than high school graduates. It never diappear in spaite of variation of  differential over time.
