Not necessarily. If most of the difference in pay goes to shareholders and/or executives, then the GDP per capita doesn't change. This could be because technology increases productivity, but in a way that increases wealth inequality, and results not only in greater wealth for the already wealthy, but less wealth for workers who are no longer needed.
