Could the euro zone become a relatively closed economy driven by domestic demand, like the United States and China?

The United States and China are relatively closed economies. This has always been the case for the former; it has become increasingly the case since 2014 for the latter . This model is suited to contemporary developments in the global economy, where the return to regional value chains and deindustrialisation are weakening global trade. Could the euro zone also become a closed economy driven by domestic demand? This is not at all the case at present , given its : Low productivity gains; Population ageing; The fact that Germany’s and the Netherlands’ excess savings are lent to the rest of the world and are not invested in the euro zone. The change of model for the euro zone would therefore require a technological investment and training drive to lift productivity and keep savings within the euro zone.
