(I am not against immigration but it has to be legal and beneficial to a country, and it has to have limits, and it cannot be harmful to local populations.)
In 1980, singer Neil Diamond recorded a song that celebrated American immigration, first in the early 1900s and then more recently. The song included this chorus:
"On the boats and on the planes
They're coming to America
Never looking back again
They're coming to America."
The song makes no distinction between the legal and orderly immigration of the early 20th century and the chaotic and illegal immigration that characterizes today's movement of mostly Central Americans into the country.
