In early-1960s Paris, Jérôme and Sylvie, both around 24, drop out of their studies to work as freelance market-research interviewers, a job that pays enough to keep them in a cramped flat but never enough for the leather sofas, English shoes and spacious apartments they study in L'Express and shop windows. Stifled by wanting, they move to Sfax, Tunisia, where Sylvie teaches, and find only emptiness and boredom there.
The effect is that their longing appears as something copied from magazines and advertising rather than something they came up with. Reading consumer aspiration this way shows the imagined self as a room that others have already furnished, where what one wants is selected from an existing inventory rather than invented.
The couple earn more than the poor and much less than the rich they copy. That puts the good life always in sight and always out of reach, so desire is fed without ever being met. Perec argues that the unhappiness comes from the gap between an abundance they can see and what they can actually afford, not from being poor in any absolute sense, and that the gap spoils even the things they do manage to buy.
Jérôme and Sylvie earn their living by questioning people about detergents, vacuum cleaners and holidays, which means their work produces the consumer knowledge that marketers then use to shape desire. Doing this job teaches them to think in the categories of the market, and their hostility to 'the system' dissolves into the same wants they help catalogue. The mechanism is that the people who study consumer desire for a living are the first to be recruited into it.
