"Today many arriving here"
are very much like those who arrived previously. And they are subject to the same discrimination your immigrant ancestors were subjected to by the decedents of the waves of immigrants that preceded them.
Here's what I want you to do. Anytime the words "this time is different" pop into your head, smack yourself and realize that, no, this time is the same. Your immigrant ancestors are no different than the immigrants entering the country today. The direction, the language, the culture, the times may be different, but it is the same. The same immigrant spirit, the same hard work, the same huddled masses yearning to breathe free.
