In a comprehensive context, even though a subject may be considered not directly useful in helping a country become wealthy, it can still contribute to prosperity through the benefits it brings when viewed holistically. Therefore, the concept of “useless” should not be applied to any subject, whether it directly or indirectly contributes to a country’s wealth.
In a comprehensive context, the first value of non-material subjects lies in their application in related fields. Specifically, teaching languages contributes greatly to the development of diplomacy. A language learner will have knowledge of how to use a phrase appropriately and contextually, which enables them to become excellent diplomats. If a country possesses generations of skilled diplomats, its relations with international friends will be strengthened, thereby contributing to economic development.
From another perspective, learning is also a way to nurture passion and thereby create joy in life, improving people’s spiritual well-being. For someone studying astronomy, their joy lies in immersing themselves in research about the solar system and discovering new constellations. For those passionate about classical literature, they find enthusiasm in studying literary works hundreds of years old to understand the socio-cultural values of past eras through each piece.
In terms of education, whether it helps individuals earn more money or live happier lives plays an important role. Therefore, the richness of knowledge plays an extremely important role and should be maintained to generate more value.
