I'm with you on classic hardwood. My dining table and chairs are older than my late grandmother, and they'll likely outlast me (may reupholster again).
But I think marketing ("express this weeks' authentic you!" says #influencer) and frequent house-moving is why disposable furniture dominates. Can't really judge people in the second category.
I'm ambivalent about this societal pathology personally - it /does/ let me buy classics for less than new IKEA would ;-)
