There is nothing natural about money. There is no link to some scarce essential form of money that sets a limit to its creation. It can be composed of base metal, paper or electronic data – none of which is in short supply. Similarly – despite what you may have heard about the need for austerity and a lack of certain cash-generating trees – there is no “natural” level of public expenditure. The size and reach of the public sector is a matter of political choice.
Which puts austerity, the culling of expenditure in the public economy, under some question. For some countries, such as Greece, the impact of austerity has been devastating.
