I started raising cain about the immigration laws in the mid 1960s, and in 1967 as a teenager made a condition for me to take over a work crew, that I could fire all the illegals and hire Americans.
For me the immigration issue was a major source of frustration by the early 1970s.
My feelings on immigration is one reason that I try to keep some distance from it here at FR.
Illegals threatened to kill my bar manager, illegals do lots of work I could do better and cheaper. I want them gone too.
