I agree with rig in that having no immigration laws properly in place and fairly enforced is no way to run a country. The question of who is taking advantage of the other is not so clear to me. We benefit in many ways from these ambitious people who desperately need money and work, but we also fail to account for public service expenditures. I just think the fence is an expensive, inefficient and inconvenient way to address the issues. A failure of Congressional leadership has allowed security contractors and others to tap into the public purse, when creativity and compromise could have served everyone in a better fashion. I still don't know how they intend to properly address the river access needs all of the riverfront ranchers, other nearby landowners, and animals, for these thousands of miles.
