First of all you seem to equate power with wealth. It may not always be the case. Power, in order to be effective, must be acquiesced.
Wealth can be of two kinds: hoarded resources, say wheat, which must be guarded and preserved or ‘cash’. The first kind is valuable only as long as somebody else needs it while the second … is valuable only as long somebody trusts the entity that coined the ‘paper’ in which the said wealth is expressed.
