Although higher education has many advantages, it also has some potential dangers. First of all, higher education may lead to students' heavy debts. Many students need loans to pay tuition and living expenses, which may lead to heavy debt burden after graduation. Secondly, higher education may lead to over-saturation of the job market. As more and more people get degrees, the competition in the job market becomes more intense, and many people may find that their degrees can't provide them with ideal jobs. In addition, higher education may also lead to the solidification of social strata. Because of the high cost and threshold of higher education, many children from poor families may not get higher education, which may lead to the solidification of social class. Finally, higher education may lead to students not adapting to practical work. Many students' knowledge and skills in college are not completely consistent with their actual work, which may lead to difficulties in their work. Therefore, we need to realize the potential harm of higher education and take measures to alleviate these problems.
