Home prices in the '80s were ~$60,000; equivalent homes now are about 10x that [0]. With inflation bouncing around 2-6% on average [1], and only modest wage increases over decades [2], that makes the median home today way less affordable even with these relatively low interest rates.
All 4 of my children, in various stages of degreedness, have told me they have no hope of ever owning a home of their own like they were able to grow up in.
True, but home prices are also much higher than in the past partly thanks to that long period of low interest rates. Taking on these huge loans with corresponding (comparatively) high rates is a different ballgame than it was in the past.

so folks have been taking on debt at current rates, and substantially higher ones, for some time.
