There is ongoing debate on whether preserving endangered languages is a logical or wasteful expenditure. In my opinion, although both views have reasonable arguments and evidence, I partly think the government should save imperiled languages for various reasons and benefits.
On one hand, spending on preserving languages brings a lot of benefits to modern societies. It facilitates the world to gain a deeper understanding of historical knowledge, cultures and events. Nowadays, as archaeologists explore antique and ancient documents, the language barrier is an inevitable hindrance to further understanding about ancient culture and eras. Those often waste a dozen of time and money on deciphering and solving ancient symbols. By preserving uncommon languages, archaeologists can have a chance to discover and notice the common grammar and punctuation rules between modern and ancient ones. Therefore reducing the time needed to analyze ancient scripts from scratch. For instance, when Vietnamese archaeologists transcribe ancient hieroglyphs script, they can use modern languages to decrease the time it takes to decipher significantly.
On the other hand, some consider spending on saving uncommon languages a wasteful expenditure for some logical reasons. While it is undeniable that preserving ones could lead to improvement of historical knowledge, it has negligible impact and benefits on the modern world and the government should spend those budgets on other aspects. In this modern day, English is the most popular language in the world because of its ease of learning, making it efficient in communication. Rare languages, in contrast, encountered several difficulties when communicating or learning, making it only appeals to a select group of learners. Therefore, the budget on preserving endangered languages is excessive while yielding fewer benefits than initiatives such as eradicating illiteracy and promoting the learning of English. For example, in the past, after experiencing war, Vietnam, rather than spending on saving rare languages in the countries, they concentrated on eradicating illiteracy and popularising education, which resulted in the growth of Vietnam economics.
While saving rare languages helps in discovering and deepening ancient knowledge, it can be considered a waste expenditure in the modern world as it has a low level of practicality in this modern world. So the government should acknowledge the current state of the nation in deciding where to spend and invest money.
