once people have tasted luxury in whatever area, it is very difficult for them to turn away from it – to come back to earth. When there is a fall in spending power, we witness a symmetrical phenomenon to the one that we identified when spending power was increased: people start cutting their expenditure on every kind of conventional product (for example, they will trade their Chevrolet for a smaller and more economic Ford), but it’s a different matter when it comes to luxury products (they will keep their Ferrari, even if it means leaving it in the garage and going by bicycle, on the pretext that it’s more ecological). They will do without almost anything, so long as they can afford the upkeep on their mansion. And there is a point that is worth noting here, one that we shall be returning to time and again: this ‘ratchet effect’ of luxury affects both the personal aspect of luxury (‘I really can’t do without the comfort of my cashmere sweater’) and its public one (‘I drive a Ferrari’).
