immigration in the nation

Before starting the immigration unit I had an idea of some of their statistics. After further research I found more information that interested and surprised me. I didn't know that illegal workers contribute billions of dollars in tax revenue as well as support to our social security and medicare systems. I feel that SB1070 is a violation of human rights in many ways. I never agreed with its proposal and I think its just a front. I haven't heard any positive news that has come from Arizona since. The bill itself didn't make sense because of all its legal jargon, but what I did understand still didn't seem logically correct. I definitely feel more informed after the research and discussions we've had throughout the unit.
