As I indicated before, in discussing the question of the family class generally, I think that if you want to assess the economic impact of the presence of the people in Canada, then you can't look only at their earnings. You have to look at the earnings of the family unit, at a minimum. It's not surprising to me that the earnings would be lower.
I wanted to clarify. You said their earnings were lower than, did you mean lower than mainstream Canadians of the same age?
