The ultimate annual increases in productivity are assumed to be 1.9, 1.6, and 1.3 percent for the low cost, intermediate, and high cost assumptions, respectively.
Note that if you look at productivity growth in the last decade, 2.5% would be a bad year. Last year's number is around 4, and the year before was around 3.5, IIRC.
Apparently, Mr. Snow is suffering strategic amnesia as to the contents of the Report he signed last week:

As my favorite economist (who highlighted this tidbit) always says: I'll stop calling them Orwellian when they stop using 1984 as a playbook.
I understand that there are Libertarian types who favor a lower-tax, less-regulated regime than I would. But for god's sake, people, the Republicans aren't your guys; they're liars and thieves and faux-religious charlatans, and if they drive the country into the ground, you'll be just as screwed as the rest of us.
