Final answer:
German consumers are indeed some of the world's most avid mail-order shoppers per capita, partly due to Germany's smaller domestic market and excellent e-commerce infrastructure.
Step-by-step explanation:
The statement that German consumers are world-leader mail-order shoppers on a per capita basis is true. While Germany indeed has a higher level of trade than the United States, it is important to understand the context of this information. The USA holds a large domestic economy characterized by substantial internal trade, reducing the relative per capita need for foreign goods.
Conversely, Germany, with a smaller domestic market, engages in a more significant level of international trade which includes a strong mail-order shopping sector. This tendency for German consumers to partake in mail-order shopping is also influenced by their well-developed infrastructure for e-commerce and shipping logistics, making it easier and more convenient for consumers to order goods from afar.
Insights into these shopping habits provide a window into broader economic trends and consumer behaviors. Such information is valuable in the study of global trade dynamics and the digital marketplace.
