Current trends suggest that developments in artificial intelligence and robotics will not result in mass unemployment but can actually create high-skilled jobs. However, in order to take advantage of this situation, one needs to hone skills that machines have not yet mastered, such as teamwork and effective communication. By analyzing data from the United Nations and the Global Talent Competitive Index, KDM Engineering found that as of 2019, the top five countries for international high-skilled workers are Switzerland, Singapore, the United Kingdom, the United States, and Sweden. Factors taken into account included the ability to attract high-skilled foreign workers, business-friendliness, regulatory environment, the quality of education, and the standard of living. Switzerland is best at retaining talents due to its excellent quality of life. Singapore is home to a world-class environment for entrepreneurs. And the United States offers the most opportunity for growth due to the sheer size of its economy and the quality of higher education and training. As of 2019, these are also some of the world's most competitive economies, according to the World Economic Forum (WEF). In order to determine a country or territory's economic competitiveness, the WEF considers factors such as the trustworthiness of public institutions, the quality of infrastructure, macro-economic stability, the quality of healthcare, business dynamism, labor market efficiency, and innovation capacity. Statistics from the International Monetary Fund (IMF) reveal that between 2014 and 2019, Japan's unemployment rate went from about 4% to 2.4% and China's from almost 4.5% to 3.8%. These are some of the lowest rates among the largest economies of the world. According to IMF, "Vietnam is at risk of growing old before it grows rich." The share of working-age Vietnamese peaked in 2011, when the country's annual GDP per capita at purchasing power parity was $5,024, compared to $32,585 for South Korea, $31,718 for Japan, and $9,526 for China. Economic prospects for some millennials have declined largely due to the Great Recession in the late 2000s. Several governments have instituted major youth employment schemes out of fear of social unrest due to the dramatically increased rates of youth unemployment. In Europe, youth unemployment levels were very high (56% in Spain, 44% in Italy, 35% in the Baltic states, 19% in Britain and more than 20% in many more countries). In 2009, leading commentators began to worry about the long-term social and economic effects of the unemployment. A variety of names have emerged in various European countries hard hit following the financial crisis of 2007–2008 to designate young people with limited employment and career prospects.
