The powers that be want cheap labor. Simple as that.
It’s not ‘just’ the cheap labor. The ruling-class politicians want a more ‘compliant’ electorate, full of foreign-born subjects who grew up in and harbor a socialist worldview... and have no real concept of American freedoms and liberty. A way to dilute the voting power of the patriotic, tea-party/Constitutionalists, who keep gumming up and interfering with their big-government agenda.
No, they want a loyal voting block. IN this crappy economy there aren’t many low end jobs either.
One day we will realize how much cheaper it would have been to have 2$ apples. In a sense the immigration debate is similar to the housing bubble. Private companies and politicians reap the benefits/profits and the taxpayers eat the losses for generations to come.
Congress now belongs to the highest bidder.
