1. Genius is rare in any country.  In the news, at the end of January, Trump did say that he wanted to "limit", not eliminate, the number of new immigrants so that only the "best and brightest" people were allowed into the country.  ------   2. Numbers???  This article claims that immigrants "make the U.S. economy 11 percent larger each year".  Since the U.S. economy is only growing at about 2 percent per year, what is it that is subtracting 9 percent from the 11 percent?  ------  3.  This article claims that immigrants have little impact on average wages "in aggregate".  "In aggregate" presumably means that the huge compensation paid to company executives brings up the average "aggregate" wages?
