I don't think it's quite as gloomy as all that, but I do think the bubble has burst, or at least is leaking a little.
The tech bubble was an overvaluation issue with virtual "assets"
08/09 was the housing bubble
What we're seeing is a supply and demand issue for the most part(the rest being supply chain issues). Demand, driven by a pandemic went up at the same time that the ability to manufacture said units went down, adding to the backup.
I think what we'll see this year is again, driven by supply and demand. Supply is catching up and demand, while strong, seems to be level. Maybe it's the time of year, who knows. Regardless, by next fall I think inventory levels will have mostly recovered for new units and that will push down used prices.
