illegal immigrants

An issue that has always struck my attention is illegal immigration, I am a first generation here in the United States fortunately my family does not suffer from deportation for the fact that we are all legal citizens or residence. But through my observation in other people I have been able to see the pain and frustrated of being singled out as being different and not among them. I wonder why does the color pigmentation make such a difference. I understand that the majority do enter illegally but the entrance is due to a push pull effect,

The push factor is that Mexico is a third world country, and the economy is basically very low to support all the nation

The pull factor is that we are hiring for cheap labor.

We cannot say we do not want them here when you know they are behind the scene in Olive Garden and almost every restaurant you step in. There has got to be a better way
