I blame ...
Take a long hard look at many things you take for granted and realise just how barmey they really are, unless you consider how economics works. Planned obsolescence (washing machine falls apart within legislated years + 1 day) is an obvious consequence of wanting sales to be repeated and profit maximisation. Some firms will aim for a different solution to the formula - eg Miele in that space - by pricing high and generally lasting longer but they really dance to the same tune.
To take perceived value to one ridiculous extreme, a Bugatti Vayron costs in the region of £1M and a modern Ford Fiesta costs say £10K. Is a Veyron really "worth" 100 Fiestas? Reduce them to raw materials and compare value or look at the amount of research time that went into each (my money is on comparable or more on the Fiesta). Both can transport near enough the same number of people but the Fiesta (I think) has a bit more room. The Fiesta almost certainly has more boot (trunk) space.
This seeming nonsense with spinners isn't really incomprehensible and we are all complicit. It is the way of the world and always has been, it's just a bit more complicated these days.
