Firstly, at school and university, what group A gain is almost theory, theory and theory. Of course, theory is very neccessary, however, you can’t do everything with theory. You must have praticeable experience. This is what group A lack very much. Although in the third of forth year at university, group A can be apprentices in some companies, to help them approach their future jobs, they aren’t trained well because of short time. And the real job is still very strange with them. After graduating, without experience, group A can’t accomplish their work perfectly. On the other hand, it takes them time and money to keep up with other experienced ones and may be scorned. Therefore, group A can contribute less than group B who have the most two important things: skills and experience.
Secondly, as group A is contributing less, they surely get less benefit. Moreover, many companies which employ people in group A have to train them from the back-ground. These companies take this cost from group A’s salary to get rid of the fact that their employees may leave after being trained to other companies. So, less benefit is unavoidable and certain, Whereas group B members are more loyal and effective workers. They also have useful experience and skills. Besides, their education is the same as or even higher than group A. As the result, group B gets more benefit absolutely.
In conclusion, I think student should travel or work before going to the university. That way, not only will they have basic knowledge but also skills
