One could use the same 'reasoning' over one's transportation ('spensive cars, raucous motorbikes..?). Hifi systems, for the television, even, whilst sounding off about how rubbish the programmes are..? Coffee machines, anyone..? Diminishing returns, probably, and very far from the stuff, in any of these 'genres' enjoyed in the '50s, where folks had exactly the same concerns about their apparat, but didn't know what was to become 'indispensable' a few decades later.
T'will all change in a year/decade/generation from now, as other stuff comes to the fore as being 'indispensable'. A lot of it is, it seems, to me, the 'grass is greener' effect, and emperor's new clothes. Maybe folks, despite 'austerity', have too much disposable income..?
