It has long been speculated that money predates writing because the earliest examples of writing appear to be records of monetary debts—meaning that the closely intertwined chronology of the development of writing and money will make it impossible to find a written history.

A sovereign government's budget is not like the budget of a household or firm. Governments issue the currency, whereas households and firms use the currency. As the chartalist, or modern money approach, explains, modern governments actually spend by crediting bank accounts. It really just amounts to a keystroke, pushing a key on a computer that generates an entry on someone’s balance sheet. Government can never run out of these keystrokes.

Money as a medium of exchange becomes important when workers are paid in medium of exchange rather than in wage goods directly. Since wage goods constitute the majority of goods produced (particularly in the early stages of development), it is tempting (but misleading) to focus on exchanges and on money as a medium of exchange [like the neo-classicals]. Once capitalist production dominates the economy, money becomes universally important: money operates as a medium of exchange and money hoards provide a measure of security. However, production involves goods and services now in exchange for a promise to pay in the future. That is, money is involved in the production process because production is time-based and involves debt commitments. If one only focuses on the use of money in exchange or as a store of value, one ignores how money creation is inextricably related to time-based production in private property economies.

The true order of events shows that orthodoxy clearly has reversed the process through which investment is funded. Banks do not begin as intermediaries which accept deposits of 'savers' and then make loans to 'investors', for this would assume that the public has already developed the 'banking habit'. This habit is the end result of public experience with short term bank liabilities which have been created as banks extend short term credit to finance working capital expenses.
