Do illegal aliens really believe that this country needs them for their hard work?

Only corrupt agricultural and livestock giants like tyson and natural foods will use thier labor as a way to increase profits to the big men..CEOs etc.. In reality there are plenty of legal immigrants whom need work and even without the legal immigrants there are agricultural machines that could do most of the work if not all. They don't utilize them becasue it is cheaper to hire an illegal if they can get away with it...as corrupt as that is.Poor Illegal aliens are not the backbone of America,,they don't do the jobs that American's won't..they do the jobs that Americans CAN'T get hired to do because they are a citizen...there is a difference. illegal immigration is decaying the economy and social services of this nation...enough is enough..no more pity for illegals
