The truth is we don't know what the future holds, and it's pointless for the Government to try to guess what the population should look like in 30 years' time, when the economy will be completely different. New Zealand businesses need skills to grow and to be globally competitive, which, funnily enough, lets them employ more locals and get them into higher paying, more interesting jobs. They just can't do it with the population or the migrants that are already here, especially when so many skilled migrants here are now leaving the country for better opportunities and to be treated fairer offshore. No economy in the world functions well like that.
