I just read the below from https://www.watoday.com.au/business/...10-p55u9a.html
"Not only does household consumption account for more than 60 per cent of economic activity, the thrifty mindset also complicates attempts at government stimulus, because people might choose to save the proceeds of tax cuts or payments. And when consumers are so cautious, businesses are also reluctant to invest their capital."
Klystron the Keynesian economist!
