Peoples entering in USA without visa or immigration basis.

hi, we the people of USA who are working hard and paying all kind of taxes to the government.
nowadays, millions of illegal peoples are working in USA. those peoples do not have any contribution in development of USA economy.
on the other side they are creating unemployments in country, lower down government income from income taxes of illegal peoples, their private businesses and jobs they are doing. and increase unemployment expenses of government. we are working hard and paying all kind of taxes to government.
private companies/businesses can get cheap illegal employees... and result in no job for legal peoples.
