Someone once said, "There are lies, damn lies and statistics."
Statistics can be very misleading. This article talks about 40% of boomers owning their own homes at 27 years of age.
Home ownership was definitely a dream of young Australians in the aftermath of WWII. It was a time of owner builders mortgaging themselves to buy a block of land. The first building was often a large garage where they lived while a modest timber frame house was erected on weekends and after work. People on lower incomes were able to get mortgages from building societies. Banks wanted loans repaid quickly and charged higher interest rates.
Hubby and I were beneficiaries of building societies. The first mortgage for the land was taken out when we were both 20 years old, still legal infants. We lived with Hubby's parents for nearly 3 years until it was paid off and then we had a house erected on the vacant block. The mortgage on the house was set at an affordable interest rate of 6% and we finally owned the house in 1985 when our children were 18 and 22. I had worked outside the home for most of that time, and we were savers.
Talk about boomers "owning" their first home in their 20s is a nonsense. Sensible use of statistics requires sensible data to be collected. Sensible statisticians do not use words like "gobbled up’ nearly one-third of America’s wealth share". I don't imagine that they use ill-defined categories such as "boomer generation" which is a very large cohort. You need to compare like with like to arrive at meaningful conclusions.
