What's wrong with this paradigm?

An Argentine opinion on the Global Financial Crisis, describing the whole Global Financial System as one vast Ponzi Scheme. Like a pyramid, it has four sides and is a predictable model. The four sides are: (1) Artificially control the supply of public State-issued Currency, (2) Artificially impose Banking Money as the primary source of funding in the economy, (3) Promote doing everything by Debt and (4) Erect complex channels that allow privatizing profits when the Model is in expansion mode and socialize losses when the model goes into contraction mode.

Its hard to escape the politics in economics. The premise that finance works when it supports the economy and not when it is central to it seems inescapable.
