It is true that the older generation has traditional thinking and is no longer useful for the younger generation in at present. I agree with both, I believe that tranditional traditional values or modern values still has have its their own right and helpful points at that moment.
In fact, the younger generations was were born in modern society where is with no war, poverty, worry and has having gender equality. Life is easier than that in the past so the young people has have an open lifestyle, focusing on social relationships and their interests. Furthermore, the social economy is growing and more diverse, the people have many options about their careers and marriage (Câu này có thể dùng cấu trúc càng ... càng thì hay hơn). There has exists so much difference many differences among the two generations. Perhaps, that is why the opinions of the elder generation is are no longer relevant for the youth. But sometime, the traditional ideas are still right. (Nên bỏ câu này đi vì đoạn này chỉ nói về modern ideas)
Certainly, some traditional values are still useful in modern life. For example, the older generations great importance to be the best ???, working hard and comparing themselves to people who are better than them is the best way to improve. These can certainly help the younger generations against the competition of labour market. In addition, traditional behaviors are still evaluated polite politeness, bring the beauty of culture and should be preversed for the next generations with respect.
Finally, I think that the young people should be selective in the way living, behave behaviour, thinking to lead to happier lives and the society is getting better and better (Mình không hiểu ý này lắm, không thấy liên quan tới vế trước, nên diễn đạt lại). In conclusion, it is right that the opinions of tranditional traditional generations is are no longer really helpful in today’s life, but that it does not mean that we (informal) people should completely eliminate all traditional values.

Ví dụ young generation bạn có thể dùng the youth, the young, young people .....
