First of all, people pay more and more attention to education now. In the past, people thought that going to school would only waste time and money, so it was better to come out to work early to support the family. Now, your concept of education has changed, and you have found the importance of receiving education. Therefore, our parents will teach us that it is always good to study hard to get a way out, and it is always good to learn more knowledge. This is why there are so many college students now.
The second is that, at present, it is better to find a job after going to college. There are more and more people now than before, which has caused great employment pressure. Therefore, in order to find a good job in the future, students nowadays will choose to study. And the university is the place where we receive the best education, and it is also one of the diplomas of our work. As far as homework is concerned, it is definitely easier for college students to find a job than for high school students. The higher the education, the more things you get and the better your job.
The third is that today's children are more eager to learn and have more conditions to learn. They think that college can broaden their horizons. Indeed, college has more contact with things than high school and junior high school. Besides, college life is also very beautiful. Many people choose a comfortable college life in order to avoid work. Others love learning and are eager to accept better and broader knowledge. So they all choose to go to college. Another is that universities are relatively easy to take exams now, so there are many college students now.
To sum up the above three points, it is normal for college students to be everywhere now. I believe that in the near future, graduate students will also become a lot.
