Sure, we took the Statue of Liberty seriously at one time and took the Celts, Slavs, Greeks, Germans, and Italians. Once the Jews wanted in, we put in place quotas and restrictions to keep them out. That worked out so well, unless you happened to be a Jew fleeing the Holocaust, that we expanded the restrictions to keep all those folks with brown skin out.

True, we did eventually relax some of those quotas out of shame. However, the fact remains that if there were a Carnegie today he would be a brown-skinned Dreamer and we would deport him before he could add to our nation's abundance.
