Immigration laws?

American imigration laws are not very much enforced to begin with, Its not that we need new laws, all we need is to enforce the laws that are already in the books. Its a well known fact that America is dependent on the cheap labor that is being generated by immigrants, who come out here and accept lower wages and labor standards, government officials always look the other way on this issue, because there is always someone out there making a profit, who is also making huge political contributions on the side. Its been this way for many years, and it wont change anytime soon, if ever.
