I have studied both in Vietnam and the US. IMO, Vietnamese students are more creative than people generally believe. However, we may seem disinterested in certain subjects because we are required to learn topics that we find uninteresting, which has its pros and cons. If you love the subject more, you will realize that what are not learning by memorizing. Moreover, you cannot make up theorems or facts! Instead of memorizing, I think each of us should be putting more efforts on truly understands the material.
However, as the Vietnamese education system requires students to learn a large number of subjects, I believe it should be customized to cater to individual students' needs, rather than adopting a one-size-fits-all approach. If the learned knowledge is not applied, it is likely to be forgotten, and obtaining a job requires a deep understanding of specific subjects or areas. This approach does not only benefits individuals but also the economy as a whole.
I have observed that this situation is not unique to Vietnamese students. Cheating is a prevalent issue in higher education in the US, even at prestigious colleges and universities. I have witnessed both domestic American and international students from other countries cheating on exams and homework.

During the time in US, I also have met people who have chosen their majors solely because they believe it will lead to high-paying jobs, and obviously they appear disinterested during the class. Thus, I strongly believe that this problem is not a result of the education system or societal factors, but more about individual.
Looking at Asian countries, how did we grow so much despite being colonized for years? It's because of our culture of obedience. You may think what you have learned is boring, but believe me, it will pay off in the future. I was once a rebellious kid who loved to talk back to my parents, but now I thank them for forcing me to study so much because it has helped me to get where I am today.
I think that one thing lacking in young people is the knowing what they truly want. This is not limited to Vietnamese students, but applies to many children of competitive parents, which is the case for most Vietnamese families. However, pursuing our desires should not mean blindly following them, but also considering the risks and opportunity costs associated with our choices.
