That's inaccurate. It's actually caused by an increase in median wages and number of people employed. Wage growth is affected by money supply growth.
That is the economic definition of inflation.
Redefining inflation is a common acting of politicians et. al who want to obscure what they are doing to the economy.
No it isn't. From Wikipedia:
"In economics, inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When the price level rises, each unit of currency buys fewer goods and services. Consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy."
