Biden’s supply chain plan is a step in the right direction
Before the Industrial Revolution, all manufacturing was local as transportation costs were prohibitively high, unless the goods could be shipped by water. Every town had its own cobbler to make shoes, for instance. With the coming of the railroads in the mid-19th century, national markets could develop. A shoe factory in Worcester, Massachusetts, could now be competitive everywhere. This led to vast economies of scale, bringing down the price of goods and thus increasing the demand for them. After World War Two, global trade increased by orders of magnitude, thanks to both the great lowering of tariffs and other trade restrictions and to the invention of the shipping container.
