australia's very own subprime crisis looming, page-184

"what's the average unemployment rate for Australia for last 20 years?"

Around 7 % . The last 20 years also falls into the very loose monetary system introduction called the fractional reserve system so property prices had an extraordinary amount of leverage even in down times..
This system has to peak out at some stage. Possibly not yet though.

Do you know what the average unemployment has been over the last 100 years?
