Emigration of Germans to the USA is only 10,00-15,000 people per year since 2000 and is trending down especially since 2016 to lowest levels ever. Emigration of US citizens to Germany started from almost nothing around the same time and is now trending up to almost 1,500 people a year. We are talking about a small number of decidedly non median people in either case but even then the rate of change is clear, neglecting the fact that Germans learn English in public school while Americans typically don't have public schooling in German. My family is descended from German immigrants who came during the 1930s to escape right wing authoritarianism.
