March 1. More than 4,000 millionaires emigrated from Germany in 2016, compared to 1,000 millionaires who left the country in 2015, according to the 2017 Global Wealth Migration Review. Before the migration crisis erupted in 2015, millionaires were leaving Germany at the rate of only a few hundred per year. Most of Germany’s millionaires, citing deteriorating security, left for Australia, Canada, the United States, Dubai and Israel. The mass exodus of wealth is hollowing out Germany’s tax base at a time when the German government is spending tens of billions of euros for the upkeep of millions of refugees and migrants from the Muslim world. The report’s editor, Andrew Amoils, warned that the wealthy are a kind of early warning system for society. Due to their financial status, education and international contacts, they can emigrate more easily than others. Over the longer term, however, their exodus portends increased emigration from among the middle class, according to the report.
