Not clear what you're even implying. Cost of financed goods was lower in 70s and 80s due to higher rates.

So when people talk about how easy it was for the last generation to buy a house or pay for college, part of that was due to higher rates suppressing prices.

The lower rates go, the higher prices go, and the ability to live a debt free life becomes diminished. Some say it's ok because the lower rates offset the increase in price.
