The ability of humans to purchase inexpensive manufactured goods in larger quantities over the past hundred years can be primarily attributed to the energy stored in fossil fuels, which has dramatically changed the landscape of production and transportation. The advent of fossil fuels led to significant advancements in manufacturing processes, enabling factories to operate with greater efficiency and produce goods on a much larger scale than was previously possible.

This access to abundant energy sources facilitated the development of machinery and automation, which streamlined production lines and reduced the labor costs associated with manufacturing. As a result, the cost of producing goods decreased, making them more affordable for consumers. Additionally, fossil fuels have powered transportation systems, allowing for the efficient distribution of these goods to various markets, further lowering prices through economies of scale and competition.

In contrast, while laws regulating international trade, the establishment of department stores, and increased educational opportunities have all played roles in the economic landscape, they do not directly address the fundamental impact that fossil fuel energy has had on the production and affordability of manufactured goods in the last century. Thus, the advantage provided by fossil fuels represents the primary driver behind the increase in the quantity and decrease in the prices of manufactured goods.
