borders are as extant as time or justice, which is to say they're a made-up concept that exists with a purpose. Immigration does have a purpose, unless we're going to suddenly get rid of all countries and go to a stateless society which isn't any time soon. People deserve to be able to have the laws and benefits of citizenry apply to them. Illegal immigrants effectively get the shittiest end of the stick by contributing to a country and receiving almost none of the benefits. The biggest problem with illegal immigration in the US is that the immigration courts are so backed up and underfunded that legal immigration is damn near impossible, forcing people into precarious and sometimes even dangerous situations. if you don't think that's a legitimate concern, then I have nothing else to say to you.
