I think that a country should only open its doors to immigrants only when there is a shortage of laborforce (when there are too many jobs and not enough people to fill those spots) such as the fields of constructions, farming etc. It should only happen such as that the citizens should not loose their jobs to the immigrants. If this happens then the country would have a lot to win because these immigrants need to buy food, cloths etc. thus increasing sales for the local merchants. However problems occur when the owners would prefer to hire a immigrant over a citizen because of the low wages. When this happens one cannot blame the immigrants but the business owners that hire them. If the business owners fire the citizens and hire immigrants because of the low wages then the responsibility falls on the business owner who has no ethics.
