and if it was true 1

I sincerely hope that the author is wrong or that the figures are wrong ... But unfortunately I see that the author's conclusions were right ... He had expected the decline in family allowances and the end of their universality in favor of migrants ... I issue some doubts about the origin of the financial crisis explained by Hispanic immigration to the USA. But my biggest regret is that I find no argument other than moral or solely of platitudes ("Immigration is an opportunity for France" (a chance to disappear? A chance for immigrants?) " France is a land of welcome "(since when? 1970?) to counter intellectually or statistically theses developed in this book. (same for books and Tribélat Obertone that address related topics). I would like to authors, books that take an opposing argument, but where the hell are they?
