Economic theorists, heads-up. My hubby Dave has walked by many works of fine art, concert halls and astonishing vistas with only the barest nod in the attraction’s direction, which is why I was stunned as we walked through the business section of Vienna to hear him say, “Oh, Adam Smith!” as he walked past this statue that, you will notice, only says A. Smith. How did he know the statue honoured Adam Smith? It turns out that Smith is the author of An Inquiry into the Nature and Causes of the Wealth of Nations. It was a pioneering work of political economics. I did not know this, but it goes to show something. I’m not sure what, except that it underscores that Dave knows a lot more about monetary systems, economics and investments than do I.
