Now that things have settled a bit, people can look at this whole corruption thing. It's amazing that the Chinese have been so open about the earthquake, that they are having trouble nailing this one back down. At least they aren't being attacked for causing the earthquake in the first place! (Dam!) :) Or maybe it was the big Sumatra earthquake increasing the thrust load?
But to put these things into perspective, it's just as bad in the rest of the developing world. Everybody puts up a building that can hold a coat of shiny paint! The incentives are all in putting up the building cheaply, using coat-hanger steel, and cheesy concrete (like the French!). Very few countries have the civic infrastructure to combat this.
Here in Canada, as in northern Japan, we have snow loads to keep us honest. They rest of the world has only infrequent extreme loads. In the States, they just give up for tornadoes and hurricanes, their cheap houses can't stand up to anything! Wait until there is a New York earthquake, then you'll see some corruption!
