Where did I say that?
I understood the phrase as soon as I heard it, as did just about everybody. I've always thought it to be the best way to solve the enforcement problem. A fence only gets one chance to keep out an illegal, obviously. That's why "self-deportation" that actually happens is more frightening to an illegal than simply "deportation", which may sound scary but is a lot less likely.
One ironic fact is that, simply by restraining economic growth, Zero himself has accomplished a lot of self-deportation and self-non-immigration.
OK. I wasn’t sure.
