Migrant studies counter negative images

My opinion for this article is that the United States, without immigrants, wouldn't be as efficient as it is right now. I dont think Americans would take a minimum payed job, but on the other hand an immigrant would take any kind of job as long as they are working and support their family. This is why there is no job competition. i dont think that immigrants are the ones causing more crimes and braking the laws, i say more americans are comitting more crimes.
