If they live "under the shadow of fear" it is a shadow of their own making. Personal responsibility.
True. But, we also have a personal responsibility to not tempt others into crime. For example, if you leave a pile of cash on the seat of your car with the window down next to a sidewalk in a town where no one knows you and a kid who's never stolen a thing in life walks by and takes it thus starting a life of crime... you are guilty of baiting that kid into a life of crime. As another example, if you give a crying kid candy you are making that kid into a spoiled brat. Who's to blame for the spoiled kid? Who's to blame for the illegal taking advantage of the anchor baby process? Here kids try this free candy it'll make you feel good.
Responsibility is not always a one way street.
The United States existing as a powerful, prosperous nation cannot be reasonably construed as some kind of irresponsible "temptation." That is one of the most absurd things I've read here since what's-his-name's last post.
Clearly you have not seen the full page ads the democrats run in mexico inviting them to come here for welfare.
