Thus the Financial Times today. “Population forecasts show why migration is an economic necessity,” explains the newspaper. According to a recent report of the European Commission, the net migration into Britain will amount to more than nine-million people up to 2060. Net migration into the European Union will total more than fifty-million up to that year. If these forecasts are accurate, the political impact of immigration will reverberate across the subcontinent, not only in Britain. But Britain is forecast to become the Union’s most populous country with more than eighty-million people. The report’s most important conclusion is that European societies are aging so fast that the Union will in 2060 have only two working-age people for every person aged over sixty-five instead of four, as is now the case. Of course, the Commission’s report does not take climate change into account. If the upcoming catastrophe takes hold by 2040 or 2050, the number of immigrants is likely to be at least a hundred-million by 2060, double the projected figure. By 2100, the figure is likely to quadruple at the very least. In the event, Europe will get new blood all right, but it will hardly be the Europe we know.
