US Gov: Our tax cuts are better

Here's some interesting language which I noticed in a press release issued from the Whitehouse [yesterday] regarding a few budgetary facts:

Since The Tax Cuts Took Full Effect In 2003, Our Economy Has Added More Than 8.2 Million Jobs In 46 Months Of Uninterrupted Job Growth. In addition, since tax relief legislation was first enacted in 2001, our economy has expanded by more than $1.9 trillion - an amount larger than the entire economy of Canada.

Is that a dig or just a friendly comparison? Methinks a few republicans in Washington could be developing a bit of an inferiority complex due to our rising dollar?
