research paper brainstorming!!!

I am planning to do research paper on mexico as its relationship with U.S is little complex and complicated.The topic of immigrants is very huge and wide to discuss but i will focus more on the way mexicans were treated brutally in America despite the cheap labor they provide to the Americans.In this country the labor cost is sky high and if the people like mexicans ready to work for some reasonable money it is very helpul for every Americans.But at times Americans misuse them by giving low wages and demanding more work from them.In the movie Farmingville it is very disturbing to see how some young american guy beat mexicans workers.They lie to them that they are taking them for work instead they took them to the lonely place in a basement and attack them brutally with stick and all.And they ran away from the place leaving them to die in a pool of blood.
