Many countries now have people from different cultures and ethnic groups It can be seen that many countries are composed of people who come from various ethnic groups holding different cultures. In my opinion, there is a range of reasons for this phenomena and it would be a positive development in terms of some countries which lack workers. In my point of view, there are two main reasons for this situation. First, outstanding talents prefer working in somewhere has more opportunities and better salaries. Mega-cities, such as New York, London, and Tokyo, are some ideal locations for these professionals because many multinational companies tend to set up their branches in there as well. Therefore, these cities would have more people from different backgrounds. Second, in some countries, such as Singapore and Taiwan, are lack of working force. Due to the fact that the number of labors is considerably decreasing, the government has taken more actions to deal with this issue. One of the solutions is to attract more foreign workers to meet the inadequacy. That’s another reason why some countries have various foreign inhabitants. For the reasons mentioned above, I believe that a country who has lots of people from different cultures and ethnic groups would have a positive development, for some countries, such as Taiwan in particular. For one thing, Taiwanese probably could improve their international competitiveness by attracting more people from different cultures. People may get used to interact with foreigners and get more understanding of global news. Besides, policies which attract more foreigners to work in Taiwan can make sure the companies and government have enough employees, and these are very important to keep the competency of industries. In conclusion, there are a variety of reasons which show why many countries have lots of people from different backgrounds. However, I believe that it is a better development in terms of some countries who have a lack of labors and international sights.
