I do not know about the author’s motivations. Perhaps your suspicions are well founded.
However your argument for the strength of the US economy compared to other economies is weak. Recovery will take bitter medicine that no one wants to swallow. I am convinced that the stimulus will not bring recovery. It will just kick the can down the road. However, the stimulus will balloon budget deficits at a time deficits should be shrinking or at least stable. In addition, the rats have a multitude of programs aimed to lower economic growth over the long run (CO2 taxes, much more employment regulation, labor union coddling, nationalized health care, renewable energy mandates, looser litigation laws, much higher taxes on producers, ...). These programs combined with the very large deficits indicate serious long-term problems. Other countries that swallow the bitter medicine now will have a big advantage in the next decade. Other countries have moved in more conservative directions. The US is moving to big-time socialism with wealth and power concentrated in the enemies of economic freedom (labor unions, environmentalists, trial lawyers, and politicians).
This study by two UCLA economists says that The Great Depression was created by FDR's economic regulations: http://newsroom.ucla.edu/portal/ucla/FDR-s-Policies-Prolonged-Depression-5409.aspx
