The rich. aka the deckstackers.
Yeah, particularly the ones that can print and legally distribute as much money as they like. They can get great nations into debt virtually overnight, and then fiscally control them to their detriment or benefit, plus virtually all the population within those nations who will not only be under the national debt but a personal debt also.......as is seen and done today.
Money is power, and there is none more powerful than those that control and print money, and have done for many, many years.
