In particular, what are the other major parts of GDP?
I guess wages. But there must be something else?
In the 60s, unions were stronger in the US, wages seemed to be at a relative high, but on this graph, corporate profits were too (as a % of GDP.)
Since then, wages have been stagnant, so it's hard to believe they have increased as a % of GDP. We have the figures for fluctuating corporate profit. Where did the other bit go?
