You are being dishonest cerhob because I think you know quite well that the home loan mortgage rate was still regulated in the days of Frazer/Howard.
In other words it was kept down to a certain level by government regulations.
Had it been deregulated as was the case during the Hawke/Keating years and today then the home loan rate would have been much higher at the time of Frazer/Howard probably around 19%.
So lets be fair eh and stop comparing apples with oranges.
