Factoid: US economic expectations in 2010

The WSJ today (A2) says that the US Government predicted in 2010 that growth from 2010 to 2015 would be 3.9%/yr and unemployment would drop from 10% to 5.9%. Growth was 2.1%/yr and unemployment dropped to 4.9%. The difference between growth and unemployment is anomalous; perhaps we are mismeasuring one or the other.
