Alchemy in the 21st Century

An editorial normally contains text without figures, tables or pictures. This one is an exception because any person can easily discover the editorial message just by reading the accompanying Table 1. It has three columns: the first is a list of the countries, ranked by their gross domestic product - GDP - in the second column while the third shows the value of the chemical shipments in each country. The GDP and chemical product from each country correlate well: the richest countries are also the world top chemical producers and vice-versa. However, there are a few exceptions: China, Brazil, India and South Korea rank higher as chemical producers than according to their GDPs. These four countries have one feature in common: they have fared well above the average since the global economic crash from 2008.
