 Criticisms of the credit theory tend to be normative and focus on the risk of overexpansion of money, that is, that states (and banks) can overuse their “printing presses” which may lead to unsustainable debt levels, excessive inflation, financial instability and economic crises. These are sometimes seen as arguments for a return to the gold standard (Rothbard 1983, Schlichter 2014). However, others argue that the realization that money is socially constructed is the best starting point for developing a more sustainable and equitable monetary regime (Graeber 2010, Pettifor 2014). We will return to this political debate below  (section 5.2).
