I think it's generally a short hand. The question, I believe, is whether the economy needs immigration to meet it's full potential (whatever that means).
The answer is no. But more importantly we can’t treat immigrants in the abstract. Not all immigrants are created equal. Not all countries are equal. Are immigrants from Japan πŸ‡―πŸ‡΅ preferable to Mexico πŸ‡²πŸ‡½?
