Nov 14, 2015 at 3:52 comment added HRSE I disagree with you conclusion that banking, ATM cards, etc. are the large part of what has driven economic growth (although it may contribute some part). It would be more precise to say that they have increased $V$. However, an increase in $V$ does not necessarily cause growth, especially over large time distances where prices are essentially flexible.
