The projects that beat inflation but do not offer positive real returns effectively reduce society's capital stock, but are nonetheless a rational alternative for investors because they reduce their capital slower than the depreciating currency. These investments are what Ludwig von Mises terms malinvestments—unprofitable projects and investments that only appear profitable during the period of inflation and artificially low interest rates, and whose unprofitability will be exposed as soon as inflation rates drop and interest rates rise, causing the bust part of the boom-and-bust cycle.
