Not just money alone.
Money represents LABOR.
Labor to do their unpleasant tasks to make their lives luxurious.
Idle hands of the rich.
Idol.
Each 'elite'/'monarch' requires about 5 million laborers to make their life truly 'luxurious'.
It might be more depending on how high the standard of living becomes, but I believe that is close to the correct number.
