My teacher used the analogy that for every 45 cent stamp the average middle class worker can afford, bill gates could purchase a lamborghini....another way to look at it, a lambo costs 300k...bill gates could buy 186,000 lambos brand new off the lot with the money that he is worth....thats $84,000 worth of postal stamps ...pretty nuts to think about it...cant even imagine having that kind of money so i doubt 500 a day would affect him too much lol...i bet he could spend 50k a day and not be hurting all that much hes worth 56B...so at 500 a day assuming he stopped earning interest on all his money and quit earning, it would take him 306,849 years to go broke....im sure he makes millions per day in just interest it would literally be impossible for him to spend all the money he has unless he was to pay off government debt or something radical
