I do not disagree. My own children are a good example. I am the fourth bilingual generation in the family of my father, who was a Quebecker whose parents were from Quebec and Acadia. I am raising my own children to be trilingual. I am married to an immigrant—in actual fact, divorced from an immigrant. My children are raised in English with me, attend a French school and speak Spanish with their father.
I am not the only person to be in that situation. In the 21st century, having skills in a number of languages is advisable.
