Three guys run pools, which have relatively limited power. The control is in the hands of those who own the hardware that points to those pools. And the beautiful thing is that there's no barrier to entry to participating in hashing, or in the case of Ethereum's soon-to-be-implemented staking.

It's massively parallel, with smaller hash-producers/stakers having nearly the same profitability as large ones, and nearly no minimum investment required to enter.

This is diametrically opposed to any central banking scheme, which is extremely hierarchical, with the representatives of regional banks sitting alongside high-ranking political appointees to create monetary policy and make decisions as significant as buying a trillion dollars worth of privately owned assets from large privately owned financial institutions.

The current centralized monetary scheme is the reason 42% of corporate profits since 1972 have been earned by the financial sector.
