Its not that the Chinese cannot make these things last they can like anyone else, it's just that they dont want to. Its the bosses and culture that prevent it. Money Greed and profit all go hand in hand. A Friend has just given away a microwave oven, made in the mid 1980s it was still in perfect working order, it cost nearly Ģ300 back then, would you pay the equiverlent today?Todays items are also driven by fashion., white micro's, black, stainless. Digital readout, numbers, knobs and dials, touch screens. Todays consumables just change all the time.
As a manufacturer would you rather sell 1000 food mixers for Ģ200 that will last for 20 years or 20 000 mixers for Ģ50 that will last for 5 years. I'm no sales expert but I guess most amateur cooks would go for the cheaper option.
There are a lot of us who prefer older "vintage' things, but when those vintage things were new, were not the men and women of that time looking forward to the new items coming on the market, be they cars, washing machines, TVs etc.
