I don’t care if Regan did say it, he is wrong, The United States the result of English Colonization. You could say that we were started by immigrants, but we are not a county of immigrants, and have not been since approximately 1780. Did you not notice that the Constitution says that you have to be born here to be President? 90% of the people here were born here. We are a sovereign nation being INVADED by immigrants, to say other wise is liberal communist propaganda.
You know nothing of history. The Chinese built the railroad in the mid 1800's. Africans built much of the South. Texas and California were owned by Mexico until the mid 1800s.
For the first 100-125 years of America we had no INS or border security. Anyone who wanted to come here and get a job was welcome. About 100 years ago, in the middle of a global Great Depression, people like yourself became paranoid about the Chinese over running America and demanded limitations. Since that time the INS has regulated immigration. Not on the basis of need for workers, but which ethnic group we like the least.
