Presumably this growth that the finance has supported is happening somewhere other than in the US?
US GDP today is seven times higher today than it was 60 years ago.
At the worst point in the recession US GDP dropped to the same level it was in 2005. Yes, the US GDP grew as much between 2005-2009 as it shrunk during the recession.
I'm relatively unfamiliar with this stuff, but do you really think GDP can grow exponentially? It looks like we're at the bottom of the skyrocket to the moon on your graph.
Oh - I get it now - the finance industry has provided support for itself to grow.
Completely false and absurd. Supply follows demand. GDP has grown throughout every industry that hasn't seen a decrease in its demand (e.g. railroads, newspapers, etc.). That includes technology, consumer goods, and technology. The economy doesn't exist in a vacuum. The finance industry provides capital to all industries.
