the problem is that just adding more numbers on top of numbers will eventually break the society for "poor" people
if the markets keep going up and we keep adding more numbers real estate will keep increasing in price which means rents will keep going up. eventually noone will be able to afford housing and thats where we end up in a 1789 situation where the landlords will just lose their heads and we go back to a society that functions
EDIT: what i mean to say is: they cannot win against numbers. the only reason they have not caused a revolution yet is because people are still complacent. but you can only push a person so far before they cannot go any further. thats where they either check out (which means no more people producing stuff which means we collapse back to the dark ages) or get angry (which means revolution). When the pitchforks come out all your wealth becomes meaningless
