Well, when I look it up on YouTube (because that's how most would have watched it), it's showing as being uploaded in September of 2010. So it's at least 14 years old, but the description seems to suggest that this presentation is based off one from 1996, but updated for the immigration policies at the time. So the information presented in this way has at least been around for nearly 30 years, which would also explain why this presentation is so refined when it had over a decade to improve.

But yeah, this information isn't new. It's also a really REALLY good argument against migration from Mexico to America specifically. The corrupt Mexican government even tries to facilitate illegal immigration, because they know that people fleeing is a release valve of social tension, and that if they were forced to stay those people would most likely lead to reform and revolution that the government there doesn't want.

Immigration helps nobody but the specific individuals immigrating. It doesn't benefit the nation that these people leave from. It doesn't benefit the nation these people enter into. It only benefits themselves.
