“The Magic of Diasporas”

This article discusses the benefits of rich countries opening their doors to immigrants. The author argues that immigrant diasporas can provide a spark to the economy for several reasons. Having immigrants in your country can make it easier to do business in foreign countries because of establishing contacts, fostering trust, providing a knowledge of local culture, and speeding up the flow of information. Diasporas also are positive because they spread ideas across countries and often these immigrants send money back to their home country, benefiting both the country they moved to and the country they came from. The author also argues that the claim that immigrants are a drain on the welfare system is usually untrue and other arguments against immigration lack evidence.
