Regarding the reason why learning own country of literature and history much more necessary for every school children rather than others culture. The main reason seems to be that every country has its own culture, language, and history which is why children should be taught the history and culture of their country because this condition lead to nationalism and among children. As a consequence, those people will be able to contribute with the aim of enhancing and developing their country with their future occupations. Dr. Jonas Salk can be a good example of this. Dr. Salk was an American medical researcher and virologist who developed America with his profession and research.
Keep in mind that without any dubiety, learning abroad country of culture, history and literature not only can be benefical, but also it plays an important role for building friendly relationship and collaboration with foreigners since this condition can also fruitful to better understand each other and can lead to respect between countries. Another reason seems to be that, if local humans want to study or work another country, it much more needable that knowing another country of culture because other country of citizen will be more welcome and trusted if we know about them which is why each individual ought to aware both their country and another country of culture.
In conclusion, it is accurate that learning another country of literature or history is more and more important for building friendly relationship and collaboration with other countries, nevertheless, I do believe that, first of all, every children should know about their country.
