If you multiply Real Gross Dometic Income by effective labor share, you get real effective labor income.
Real effective labor income is how much income labor recieves from national income in real $ terms. And... back in 1st quarter 2008, real effective labor income hit an all-time high of $10.539 trillion.
Real effective labor income = Real GDI * effective labor share
Real effective labor income (1Q-2008) = $13.322 trillion * 79.1% = $10.539 trillion
Since the crisis, real effective labor income has gone down to $9.654 trillion. Labor lost almost a trillion $ in effective income.
How much of that lost effective income has labor regained. Well, it should be a lot because real GDI has gone to a new high of $13.621 trillion... Let's do the math...
Real effective labor income (4Q-2012) = $13.621 trillion * 74.3% = $10.129 trillion
Labor is still $400 billion short, even though real national income is at an all-time high.
So what happened to real effective capital income... this may surprise you. Real effective capital income hit an all-time high in the 3rd quarter of 2007 of $2.980 trillion.
When did capital income surpass that number? We know they did but when? They surpassed that number in the 3rd quarter of 2009... just one year after the crisis. And here we are almost 5 years after the crisis hit and labor income is still $400 billion short.
So now the big question, what has real effective capital income risen to?
Real effective capital income = $13.621 trillion * 25.7% = $3.500 trillion
In effect, real effective capital income is $500 billion over its previous all-time high, while labor income is still $400 billion short.
I guess we found where the $400 billion of lost labor income went...
