Which brings me to the point: In order to lose momentum, the U.S. economy has to have momentum to begin with. If it had any, I missed it. What we had was a government-prescribed course of amphetamines (to keep it up), antibiotics (to prevent infection) and antidepressants (to make it feel better). It endured regular steroid injections from both monetary and fiscal authorities. And it still has no real muscle.
