The bottom line is that illegal immigration; defined as entering this country by subverting the laws set in place to regulate immigration, is wrong. I can see if people were being oppressed and came over as refugees. There are laws governing this.
I wonder what the laws are in other countries regarding people who come into a nation outside of legal chanels?
Multinational corporations who want cheap labor and various governments are in cohorts to make a ton of money. The affect of this is the displacement of people who want to work say starter jobs and the breakdown of unions. If the laws regarding the hiring of people who are illegally in the U.S. were to be enforced, it will be the small businesses who would largely be affected. Those who can't move their businesses and operations offshore.
And on this question of uniting with latinos, I will just say this: "There can be no [black-latino unity or] black-white unity until there is some black unity." -Malcolm X
That's my piece....
