Are we really depending on the Communist Party?

Here in Hong Kong I am thinking that the economies of the US, the UK and almost certainly mainland Europe are dependent on governments printing money and planning major infrastructure projects to lift them out of recession. The UK government is bankrupting the country and crucifying the currency. The US will have to wait for plans, environmental protesters and probably lawsuits before words can be translated into action. The Europeans are still arguing about the merits of the procedure. let alone the details. China, we are told, is the most efficient country at putting plans into action. Why? Because it already has cash so doesn't have the problem of finding buyers of bonds to be issued, and it is a one party state so there's nobody to disagree. The theory is fine. Will it work in practice? Thousands of workers have been and are being laid off in the Pearl River Delta, the heart of the export business, as global trade is slowing. Many more factories will close for Chinese New Year at the end of January and will tell the workers not to come back. The unemployed are already protesting. 1000 migrant workers staged a demo in Shanghai yesterday which was broken up by police, resulting in violence. How quickly can the factory workers be reemployed digging roads or building railways and will they settle for this outdoor work instead? People tell me that China must ensure 8% GDP growth to prevent social unrest. Many economists are now predicting growth of 5-6%. My observation is that political risk must be increasing in China, unless the unemployed are being swiftly reemployed as soldiers or riot police.
