In San Diego economist Alan Nevin’s book, The Great Divide: The true story of America tomorrow, he makes the case through reams of data and charts that America’s economic future is bright, particularly in the West and South. The reason? Robust immigration. In contrast, he cites the dire immigration and birth statistics of Europe, Japan, and even China, in which aging and retiring populations will burden the social safety net with only a small young labor pools to support the countries’ economies. However, this CityLab article, focused mostly on what to do with abandoned buildings – assuming little change in current demographic trends – screams out the lunacy of xenophobic immigration policies. We have both the economic need for robust immigration and the space to accommodate immigrants. But if you want to read about the recycling and environmental benefits of demolition, the CityLab article does a good job detailing this process and benefits.
