Following up on the "Magic and Miracle of the Marketplace
" post below, the chart above shows that the decline in prices over time has taken place for almost all manufactured goods, not just for electronics. As a percent of consumer expenditures, the combined share of spending on food, cars, clothing and household furnishings (furniture, appliances, etc.) has fallen over time from close to 50% in the late 1940s to close to 16% in 2010. This decline in spending over time on manufactured goods, measured as a share of all consumer spending, is really a testament to the remarkable productivity of the manufacturing sector, which leads to declining prices relative to income and services, and increases our standard of living dramatically over time.
