TheStreet.com's Jim Cramer says that rebuilding from natural disasters can alter the growth picture for a country.

Is it Katrina all over again? Or is it bigger? Much bigger? That's what I am thinking about this Chinese earthquake.

Katrina distorted the U.S.'s growth pattern for more than a full year. The raw materials, the effort, the work, the reconstruction affected businesses from small-scale retail to refining and infrastructure.

We don't really know how China works, although a lot of people tell us they do. To me, the Chinese are always a day away from revolution or civil war and the trick of the government is to stay one step ahead of the posse. (Chinese hands will dispute that, but you have to appreciate that it takes a special skill to be wrong for more than a century and still maintain credibility.)

That means massive reconstruction: bricks, lumber, cement, steel and all the trimmings. Massive imports, not controlled by the Chinese and their little negotiation games like they play with iron and steel and coal. Just full-bore buying and something that could take growth for China back to the levels that everyone thought it couldn't absorb without more inflation.
