There is a significant moral difference between a person who commits a violent crime and a person who tries to cross a border illegally in order to put food on the family table. Such migrants may violate our laws against illicit entry, but if that's all they do then they are trespassers, not criminals. They deserve to have their dignity respected.
Imagine discovering a continent so vast that it may have no end to its dimensions. Imagine a new world with more resources than all our future greed might exhaust, more opportunities than there will ever be entrepreneurs enough to exploit, and a peculiar kind of real estate that expands with development. Imagine a place where trespassers leave no footprints, where goods can be stolen infinite number of times and yet remain in the possession of their original owners, where business you never heard of can own the history of your personal affairs...john perry barlow
