This is so INTERESTING
Hans, I hadn't really ever thought consciously about this before, though it's been a motivating force, for sure.
One thing is for sure: we like what we like because of traits we associate with the material. It doesn't matter if the facts we believe about the material are true or not.
I rather detest metal objects because metal is associated with rusting, being old, uneducated, old dark color exhaust belching cars and trains, being associate with ignorant oppressive thoughts, heavy, dirty steel mills, filthy pot-belly stoves, greasy, grimy, smoking and tobacco use, alcoholism, dirty, cut your hands, rusty leaking metal septic tanks, freezing, smelly..... generally yuck. Who Wants that?
On the flip side- I much WANT plastic type things. Plastic is clean, lite weight, colored, flexible, educated, warm, comes in many forms, cushiony and soft, etc. Plastic is a vacation on a sandy beach (vs. metal is freezing sub zero Buffalo, NY winter) Plastic is electronic products and a-a-a-all that that covers. Plastic is healthy eating and progressive thoughts.
The facts? That 60 year old stove you have to cook on, I've no doubt it has plastic parts in it. And the car I drive- it's sure to have lots of plastic parts but the frame and engine is metal. The vacuums you like may have a metal body, but the cord, and handles, and hose, and the paint finish- those are all plastic or a plastic-type material. My computer- It sure has it's fair share of plastic parts, but the frame is a metal box. All the wires and circuitry are metals.
It's interesting for sure.
Then one could ask; how does one feel about wood product, or products made from sea shells, glass, etc.
And how did we come to associate things with these materials?
Was there a subliminal ad campaign that snuck by? Is it generational?
I mean I grew up in the 70s when metal was in it's hey day, shall we say. There were lots of junky metal products. The 80s were seen as fresh and plastic was certainly taking over. Maybe that's what it is.
