Some say the only motive for people to learn foreign languages is because they can able to travel to work in foreign countries, while, others say this is not the only reason for learning new languages, because they are opening the doors for plenty of other opportunities in their own home country and I do second them with this perspective.
Some say the main reason people are learning foreign languages is because people can work in foreign countries without any hiccups because they can able to communicate with natives in their local language, as a result, there is no language barrier between natives and others. they can perform their work as if they are in their own country. For example, thousands of people all over the world come to Australia each year in search of work, and it is the compulsion that you must know the English language at a satisfactory level so that you can communicate freely with Aussies but I do not agree with this perspective because learning a new language has other benefits too that people can avail by residing their own country.
Others say knowing a new can be helpful in migrating to foreign countries for work but it is not the only reason because people learn new languages for attaining jobs in their home country. There are various jobs like language interpreters that are in huge demand in some countries, therefore people are learning new languages in order to secure those types of jobs. For instance, many youngsters, in India learn foreign languages like German and French so that they can work for the Indian government as interpreters since the Indian government has lots of meetings with officials from other countries where their mother tongue is not English/Hindi. I do agree with this perspective because some countries like Bangladesh and Pakistan have more English language speakers than the UK/USA because in these countries English is the second language. If that is the case, all the population of these countries would be moving to developed countries like America or Australia.
In conclusion, it is true to say that although learning a foreign language can be beneficial in migrating to other countries, it is not the only case people are learning these languages.
