there is no enforceable way this would work. everybody would just pay some homeless/unemployed to buy him that expensive cool little thing, and give him 10 USD for the job. try to prevent that :)

at the end, poor people would become less poor, but only by screwing with system, and only very few of them. you can put some limits on who can buy what, but this will inevitably create a massive bureaucratic overhead, meaning another set of useless government jobs that create no added value, but draw cash steadily from treasury.
