Your question refers to the table found in the document titled 'The Progress and Poverty in Industrial America', Page 2, Part A.
In this document and the table within the document, we can understand how the 'Gross National Product' also refered to as 'GNP' was heavily increased, starting at $531 in 1970, and ending at $1299 in 1910.
This created a much better standard of living, and created new oportunities in American society. The average of comfort, leisure and refinement was raised.
I hope this helps you! Have a great week :)
