There should be a curve that shows inflation, otherwise that GDP curve is not as informative as it should be. Or is it adjusted with inflation rates (which by looking at the shape of the curve, is not probable).
Assuming that GDP per capita is growing faster than inflation, meaning we are actually more prosper and have more purchasing power; it's interesting that since the 1970s we are producing more and more efficiently, which would be something uncoherent considering the fact that we have had various energy crises around the world since that date though.
