Can The US Economy Ever Get Back To 3% GDP Growth?

ConvergEx's Nicholas Colas asks "Can the US economy get back to the 3% GDP growth it enjoyed in the 1980s – mid 2000s?"
White House economic policy makers say “Yes”.
Most professional economists say “No”.
History says, “Worker productivity drives economic growth, not politicians or economists. Fix productivity and you can get to 3%.”
History may not be laconic, but it has a point.
