Millions, billions, what difference does it make?

Posted 3/29/2015

John Hinderaker at Powerline comments that President Obama has been a failure, using his own economic predictions.  What I find interesting is that even a highly intelligent person makes a mistake about the size of the numbers involved in the US economy (and budget).  John writes about the Obama administrations prediction of US GDP:

Here they are, in millions of dollars, along with my calculation of the projected growth rate:

2012 16,203

2013 17,182 = 6%

Of course, that should be "billions" of dollars.  At some point, the numbers are simply too large for even highly intelligent people to comfortably comprehend.
