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.
