Take a child born in Canada this year who has: a Moroccan father who is a naturalized citizen of the US; a Swedish-Brazilian mother; a paternal grandmother who is Irish; and a maternal grandfather who is Italian. How many countries' passports can one little boy need? I doubt parents think it worth the time and money to get them all.
