I'm sorry, but I can't like this book, simply because its premises are factually wrong for place and time. Yes, immigration built countries like the United States. That was then, empty country (well, not counting the natives). And immigration is responsible for humans everywhere except for a specific bit of Africa, where we originated. Again, that was then. This is now. The empty places aren't empty. Resources aren't inexhaustible. And, adding insult to injury, today's immigrants often arrive carrying as baggage a culture that is inimical to the one already there. It's funny to me that Islamic immigrants are often fleeing their countries of origin precisely because Islamic ways aren't working too well for them, but they bring the very same failed ways with them, and get angry if the people already there aren't willing to kowtow to them. Them - "We don't eat pork! Your bacon offends me!" Me - "Well, don't eat pork, buddy, and stay away from my table!" We are in the middle of a cultural war, being fought (and lost) in Europe, and at a stalemate in the United States. We don't want Islam here. If we wanted it, we'd be the ones immigrating, don't you think? I'm happy the author has found joy and a wife by immigrating. I'm sure he isn't threatening to kill people if his new home doesn't serve fish and chips daily. He's not typical of the immigrants flooding into the West, but he writes as though they're all like him. This book fails to make any valid point. Don't waste your time on it. ( )

I suspect I am not the audience for this book - I agree with the author, and was not surprised by most of the arguments and evidence that he used, but I really struggled with both the tone of the text, and the decision to include All The Arguments (ex: I'm just not convinced by evolutionary arguments for highly social issues in general, so spending the same amount of time on that as on arguments I find significantly more persuasive) I'm not sure how effective this would be in shifting the position of someone deeply entrenched in an anti-migrant world view, or how it might read to someone living in the USA, but it was less affirming than I'd hoped. (I recieved a copy through the Early Reviewers program)

Engaging prose, a bold premise — I truly enjoyed reading this book. Immigration is a very polarizing and hot-button issue. The Author puts immigration & emigration into context from the beginning of all times through to its evolution, making a strong case for free borders’ benefits to countries and humanity in general. Additionally the Author debunks the far-right arguments for keeping immigrants out of countries. Well-formulated, well-written and a timely addition to the discourse!

A good read, good research, good points. If you were wavering about whether you thought open borders (or better, no borders) were a good thing this might persuade you, but is almost certainly not going to be engaged with by the people who need to read it. ( )
