Most of these worries are of long term deflation. If deflation is temporary and is perceived as “prices going back to normal”, as it is with cars and GPUs, I don’t think most of these worries would manifest. People aren’t holding off on buying a car because they think car prices will continue to fall long term.

It should be noted, however, that there are many ways in which deflation actually helps the rich more than the poor. Since money is worth more over time, it favours those who already have money. Conversely, inflation can surprisingly help the poor by making debt worth less.

But this assumes that rich people aren’t the very ones profiting off of inflation by price gouging, rent seeking, and manipulating the market, which they absolutely are. So I very strongly doubt that short term deflation hurts the poor and working class.
