Fiscal policy and the private sector have not done enough to ensure long term growth -- as mentioned asset inequality has lead to a lot of capital in the hands of actors that do not spend money. Advancement in technology is deflationary by nature and so a lot of growth is only realized by the top. In times like this the public sector must intervene to frame the future for it's citizens and economy: focus on the health and education of your citizens, mitigate future risk by funding solutions to climate change, secure safety by spending on military and providing equal opportunity to quell internal social unrest. If you have strong instutions and control the currency that your debt is in (US, UK, Japan, China -- as long as the communist party maintains its current strength) this is the way to go, globalization will take a hit but will cycle back in the future.
