@fribbledom Slow trend over many decades and several generations.

Possibly starting with clothes and then furniture.
My mother (now 93 y.o.) would inspect every piece of clothing and check every stitch to make sure it was well made, and if not either reject it or demand for a massive discount.
IKEA was very frowned upon by her generation. "Only last a few years", and the furniture she bought lasted a life time.

Once supply-chain logistics and Amazon came to be, the masses were already primed.
