The meaning of why many choose to leave their country of origin can be socially or culturally constructed and be very significant for the people involved. One reason why immigrants come to the US is to work and earn money for a specific purpose. Mostly young unmarried men and women who are apart of an overall strategy to provide income for the family come to the US for short periods of time and then return home. The most common reason why both Mexican men and women come to the US is due to lack of opportunities in the Mexican economy. Employers have come to rely on undocumented immigrants labor and view them as dependable and hard working.
Immigrants are willing to accept jobs that requires lots of physical work with long hours involved.
Many jobs such as farming requires 12-15 hours a day in hot, dry fields and pay below minimum wage. Most Americans would not even think twice about working in such conditions, and only consider jobs that contain high salary structures and elite social status. US citizens show greed and want more and more material items as their disposable income increases. Immigrants only want enough money for survival and provide basic living needs for their families. Crossing the border marks the beginning of the transition phase, many never gaining enough links to continue on the next phase in becoming a settler.
