Black friday is a datapoint. But maybe people are deferring purchases to these sale periods. What proportion of goods were luxury vs. not.
Also poor people can get into debt they are still poor. Maybe they can afford a nintendo switch but not afford to raise a family.
Deferring sales is one datapoint. But setting records is another datapoint and counter to deferring IMO.
Edit there is talk below of inflation adjusted numbers being high but meh
The only things I bought on Black Friday were things I would normally have bought but just waited a few weeks/months to get.
