After world war 2, economy and technology were not fully developed so people had to study very hard at that time. Even though economy and technology are fully developed now, they still need to get a high education because of social pessures.
First of all, high school students do not know how they will be going on when they graduate high school. They think that going to college or university is the best choice for them because their families told them that finding a job will be hard if they do not get a bachelor degree. For example, some companies indicate that applicants need to have at least bachelor degree and their Family Show Them To Prove. This is why they think if they do not go to college or university, they are not going to get a decent job.
Secondly, young people are not sure what they want to do after they graduate. Moreover teachers recommend to go to college or university because they think students have a chance to find what they want to do in ther next shcool life or even if they did not find it, they still would have more chance to get a decent job.
In conclusion, almost all high school students are influenced by their families about their life or social life. Their families rely on experiences of their past life to give advices to their children. However society is changing everyday so they need to know what is the most important thing for the current generation.
