How Money Became the Measure of Everything
Capitalization was key to the rise of economic indicators. Upper-class Americans began to put their wealth into new financial assets. They began to see their society as a capitalized investment and the people as capital that could be used to increase wealth.
In the North, such investments took the form of urban real estate and companies that were building railroads. Investors were putting money in communities they had no other interest in. A national business class emerged that cared less about moral statistics than about the town's industrial output, population growth, real-estate prices, labor costs, and per-capita productivity. In the South, enslaved people became pieces of capital that could be mortgaged, rented, insured, and sold.
