Sie ist es bereits. Je stärker die deflationäre Tendenz, desto grösser der Raum für den öffentlichen Sektor, durch Net-Investing und Net-Spending Einkommen zu erzeugen und auch umzuverteilen, ohne damit Inflation zu triggern.
Aggregate Demand = Consuming + Investing + Government Spending: Sinken aufgrund von Automatisierung die Zahl der qualifizierten Arbeitsplätze bzw die verfügbaren Löhne insgesamt, müssen bei unveränderter Leistungsbilanz die Sektoren Investing und/oder Government identisch ihre Ausgaben steigern, um Aggregate Demand stabil zu halten. Government steht jedoch in der Vorhand, weil Privat Investing primär eine Funktion von Consuming ist.
...John Maynard Keynes in The General Theory of Employment, Interest and Money argued during the Great Depression that the loss of output by the private sector as a result of a systemic shock (Industrie 4.0 könnte diese Qualität erreichen) ought to be filled by government spending. First, he argued that with a lower ‘effective aggregate demand’, or the total amount of spending in the economy (lowered in the Crash), the private sector could subsist on a permanently reduced level of activity and involuntary unemployment, unless there were active intervention.
Business lost access to capital, so it had dismissed workers. This meant workers had less to spend as consumers, consumers bought less from business, which because of additionally reduced demand, had found the need to dismiss workers. The downward spiral could only be halted, and rectified by external action.
Second, people with higher incomes have a lower marginal propensity to consume their incomes. People with lower incomes are inclined to spend their earnings immediately to buy housing, food, transport and so forth, while people with much higher incomes cannot consume everything. They save instead, which means that the velocity of money, meaning the circulation of income through different hands in the economy, is decreased. This lowered the rate of growth. Spending should therefore target public works programmes on a large enough scale to speed up growth to its previous levels....
...From the perspective of debt, the Keynesian prescription of government deficit spending in the face of an economic crisis consists of the government net dis-saving (increasing its debt) to compensate for the shortfall in private debt: it replaces private debt with public debt. Other alternatives include seeking to restart the growth of private debt ("reflate the bubble"), or slow or stop its fall; and debt relief, which by lowering or eliminating debt stops credit from contracting (as it cannot fall below zero) and allows debt to either stabilize or grow – this has the further effect of redistributing wealth from creditors (who write off debts) to debtors (whose debts are relieved)...
