Everyone knows that 2008 promises to be a bellwether year, rife with dramatic changes already glimpsed. Some harbingers of change are obvious. A new president will be electedthough campaigns hide as much as reveal what that president will choose or be forced to do. The subprime mortgage market also portends dramatic changes in the financial markets in 2008 and beyond. But perhaps the biggest change of all is a sleeper so farthe first year of a scheduled drop-off in employment growth that will last for some 30 years running. If this decline is left unchecked, the net impact on employment will be far greater and longer lasting than the temporary employment dip during the Great Depression.
