This most recent bit of new legislation really bears watching by the the citizens of the US. The costs stated are proving to be grossly under stated. The initial costs are likely to be in the trillions, not billions as stated. Also the provisions for illegal immigrants would make it unlikely they would ever leave the US because they would not be covered by the provisions in the law if they ever did try to return. This is another bit of terrible sham attempts to fix this problem. The weathy industrialists in the US cannot allow anything to endanger their captive pool of cheap labor. My real concern is that the ideas now seemingly guiding their thinking is, "Why not pursue the North American Union so that the issue cannot be truly addtressed. Without borders how can one be an illegal immigrant?" If passed this will be another contributing factor towards the further undoing of the US financially.
