The methodology of this report is a joke. For example, to come up with the $600 million figure, they say: "We simulated an increase in productivity growth in the exceptions using industries of just one one-hundredth of its otherwise experienced growth in the three years from 2007 through 2010 – a very conservative estimate of additional growth." i.e., they pulled 1% (net) increase in growth out of the air, and then simply calculate the economic benefits of that hypothetical increased growth.
