thermal fuses and planned obsolescence...

Recently, all toasters, hair dryers, curling irons, cooking rings etc. are equipped with thermal fuses, which blow sometime, making the device not working, also useless. We just bypass it, as it's pointless to replace it, as it will blow again, and it doesn't protect from anything.And in ovens (in normal stoves) nothing is stainless steel anymore; the screws, the sliding rails, the fan they're all normal steel, probably just galvanized. When I got to repair an oven, I change them with stainless steel ones. And I explain to my customers. that to the manufacturer a stainless steel screw versus a galvanized steel one, costs next to nothing, ditto a fan. They do it deliberately, so that the oven breaks down and you'll have to replace it. Also the steel quality has much declined; they get holes (the ovens) in a few years.
