Wealth and comfortable middle in AU (4-MAY-23)

Found this article today, but the article was written on 2-MAR-21. That’s about 2 years ago. I was googling to see what the wealthy and middle class income ladders were as I’ve been watching the episodes on how the middle and lower classes were being impacted by high interest rates and the high cost of living based on the market conditions today.
