What are you trying to say? That people that had "millions" went homeless? The stocks recovered in less than two years. If they didn't sell in panic they still had millions after a brief period.

Edit: you say 2 years... But people bought this one as well by the millions in those days; https://www.google.com/search?q=kpn+koers&oq=kpn+koers&aqs=c...
That never recovered. While 'everyone' agreed that could never happen as this time there was no roof. And for a brief moment almost everyone believed that.
As a less localized thing; in the tech community, stocks of for instance Borland/Inprise were talked about in the same way. I don't think (but cannot find info fast) they ever recovered.
