The text analyzes how shifts in the value of money create unequal effects across investors, business, and earners, transferring wealth and heightening risk, unemployment, and economic waste. It treats inflation as a form of taxation, compares currency depreciation with capital levies, and re-states the quantity theory and purchasing-power parity while explaining exchange-rate behavior, including seasonal and forward markets. Competing policy aims—devaluation versus deflation and price stability versus exchange-rate stability—are weighed, and the author offers practical proposals for monetary reform in Britain, the United States, and other countries to reduce instability in the standard of value.
