That's an improper analysis.

First off, it's dollar-averaging every category, so it's not "% of income", which varies based on unit income.

Second, I could commit to spending my entire life with constant spending (optionally inflation adjusted, optionally as a % of income), by adusting quality of goods and service I purchase. So the total spending % is not a measure of affordability.

Almost everyone lifestyle ratchets, so the handful that actually downgrade their living rather than increase spending would be tiny.

This part of a wider trend too, where economic stats don't align with what people are saying. Which is most likley explained by the economic anomaly of the pandemic skewing peoples perceptions.
