This paper discusses the financial sustainability of demand-led growth models. We assume a supermultiplier growth model in which household consumption is the autonomous component of demand that drives growth and discuss the financial sustainability of such dynamics of growth from the perspective of the working households. We show that for positive rates of growth the model converges to an equilibrium where worker households are accumulating debt and not wealth. We also show that when the economy is growing at a rate that is positive, but not too high the model also implies that households will not be able to service their debt at the point of full long run equilibrium. We then conclude that this household debt-financed consumption pattern of economic growth generates an internal dynamic that leads to financial instability.
