That's missing the point. This is not a value judgement about whether the refugees contribute to society. By being employed they are in fact helping to keep wages lower than they would be if there was a lower supply of labor. The point is that the main benefactors of immigration are corporations, not working-class families. Thus traditionally left-wing labor parties have been against immigration. We should be using immigration to shorten the workday for everyone, thus counter-acting its effects of wage suppression and giving people more time to dedicate to relationships, thus recovering the birth rate and reducing the need for immigration. Of course this will never happen, because economic growth is more important than people's well being.
