That's measuring the monetary value while ignoring actual utility. No amount of money could have bought a polio vaccine or advanced cancer treatments or genetic testing or microelectronics in 1933 but these are common things across the world now.

The biggest growth is in industrial production and distribution of goods and it isn't really quantifiable.
