Opponents argue that people who come into contact with society too early, driven by financial interests, stop studying their majors hard, only remember that they can make money and can't grasp the foundation at all. At work, the basic knowledge is not solid enough to adapt to the variability of future work. Maybe they can get wind and water at first, but they have technological innovation. People who work hard at school can adapt immediately, and those who set foot on their posts too early have no time to learn more and deeper, but they are passive and serious and jump ship directly.
