Earlier quoted context omitted.
I have lived in "luxury" apartments lately and they're all filled with the cheapest possible materials. More "advanced" in that as much as possible things are build of engineered materials which end up being a sort of wood and glue foam which are definitely not meant to last.
“Luxury” is simply a marketing term and has no importance. The relevant question is how do the cheapest materials today compares to the cheapest materials in the 1980s?
The garbage materials of today didn't exist nearly as much in the 80s so they'd have to have used at least cheap solid wood instead of sawdust foam.
