While it is possible to slice and dice economic theory and give names to all the bits that don't work without other bits, (Look at all the names associated with an Anchor or the rigging of a Sailing Ship) there are really only 4 schools of economic theory.
Capitalism
http://en.wikipedia.org/wiki/Capitalism
Main Failing - Capitalists will sell anything, including their own children. Since Capitalism always results in just 2 classes, the very rich and the very poor, when allowed to run it's course - Capitalism always will end up with a revolution.
Socialism
http://en.wikipedia.org/wiki/Socialism
Main Failing - Socialism doesn't reward the capable, so the capable always migrate elsewhere if they get the opportunity. As practiced in Russia, China and Cuba - Socialism acquired a group of overlords who held themselves apart while imposing Socialism's theory on those who couldn't escape. It's easy to visit Cuba where anyone who wants to see a Socialist Society in operation can witness the lack of innovation, the lack of pride, the refusal to work and the complete lack of capital. The Soviet Union fell, the Chinese have moved on into a mixed economic system. Only the Cubans still drive 1957 cars because they are frozen in a bubble of time.
Social Credit
http://en.wikipedia.org/wiki/Social_Credit
BC and Alberta both flirted with Social Credit governments, however we never saw Social Credit economic theory put into practice. Social Credit, to work, would need a National, Isolationist Economy to be tested. The economies of the world have always been too interconnected for that to be possible.
Austrian School
http://en.wikipedia.org/wiki/Austrian_Economics
The main failing of the Austrian School is that it's a sort of Capitalism without rules. Since we already know that Capitalism will result in people selling their own children, there has never been a lot of takers on the idea of testing Austrian Economic Theory.
I don't believe it possible to govern a country and adhere to a pure form of any of the economic theories.
The USA and Canada, along with most of the Western Nations, has subscribed to Capitalism for the upper classes with Socialism for the lower classes.
Since the upper classes don't believe the money for the experiment in Socialism they are running for the lower classes should come from their purses; the experiment has finally failed. You can't run a welfare state where you have a high proportion of the population receiving benefits without contributing. Especially if the upper class is also not contributing.
I think the reason for the political panic and the demand by the upper class for unprecedented bailouts is that the upper class really hadn't realized the degree of interconnectedness in the World's economy. The upper class has discovered that they have nowhere to run. Always in the past, the upper class has been able to move elsewhere when they had stripped the value out of an area.
