A new study from the Congressional Research Service discovered an interesting interrelation between depressed middle class incomes and increased immigration. The Washington Examiner reports that in 1945 the foreign-born population of the United States stood at 10,971,146, but by 1970 it slid to 9,740,000 for a net loss of 1,231,146 foreigners. At the same time, says the CRS, “The reported income of the bottom 90% of tax filers in the United States increased from an average of $18,418 in 1945 to $33,621 in 1970 for an aggregate change of $15,202 or a percent increase of 82.5% over this 25 year period.” In contrast, from 1970 to 2013, the foreign-born population blossomed from 9,740,000 to 41,348,066, a 324.5% increase. However, “The reported income of the bottom 90% of tax filers in the United States decreased from an average of $33,621 in 1970 to $30,980 in 2013 for an aggregate decline of $2,641 or a percent decline of 7.9% over this 43 year period.” There’s no question high-skilled emigrants who go through the system legally contribute positive economic effects. The issue is that our basically open borders have allowed the population of unskilled illegal immigrants to swell, which undoubtedly strangles the overall economy. Border security must be Congress’ top priority to fix the overarching issues affecting America’s middle class.
