We can't possibly take in all the legal immigrants who want to come here. There are limits. We take in far too many legal immigrants every year. We don't need 1.2 million legal immigrants a year while 20 million Americans are unemployed or underemployed. We have just had the two highest decades of immigration in our history. In 1970 one in 21 was foreign born; today it is one in 8, the highest in 90 years; and within a decade it will be one in 7, the highest in our history.
Between the first quarter of 2000 and the first quarter of 2013, the native-born population accounted for two-thirds of overall growth in the working-age population (16 to 65), but none of the net growth in employment among the working-age has gone to natives.
The overall size of the working-age native-born population increased by 16.4 million from 2000 to 2013, yet the number of natives actually holding a job was 1.3 million lower in 2013 than 2000.
The total number of working-age immigrants (legal and illegal) increased 8.8 million and the number working rose 5.3 million between 2000 and 2013.
Even before the recession, when the economy was expanding (2000 to 2007), 60 percent of the net increase in employment among the working-age went to immigrants, even though they accounted for just 38 percent of population growth among the working-age population.
