It’s something even most Americans don’t even understand anymore, let alone foreigners or immigrants; that the USA is technically by design 50 countries, in an economic and organizational block for limited purposes.
The core, supreme law of the land, the Constitution is explicit that anything not explicitly delegated to the Federal government is the right of the state and the people. The vast majority of what the federal government claims rights over is not mentioned at all, let alone explicitly delegates to the federal government. Included in that, banks and regulation of banks.
Unfortunately, the founders of America were not positively explicit enough about the sovereignty of the states, probably because they had no understanding of the consolidating forces that would be introduced through things like automobiles, planes, roads, electricity, telecommunications, and computers and the internet.
The small banks thrived and why America’s banking sector was so “fragmented”, was by design, in hopes of preventing the very consolidation of power and control that the founders were so concerned about and threatens everything now. American banks were community scale, community oriented, community based, and had community accountability; all factors that restrain psychopathic tendencies of banks and bankers.
If these forces of evil that are trying to consolidate everything are not able to be stopped, by all measures things will only get worse for all of humanity from here. Just as banking has become stale and uniform and conformist without any real diversity, so will those pressures continue destroying real diversity in the world by trying to force everyone and everything into templated, repeatable objects for global uniformity.
There has been no time in human history where consolidation of power was a good thing. Monolithic things fail spectacularly. I would argue that the degree of global consolidation of power lusted after by globalists even represents an existential threat to humanity, if not all life on this planet. It creates a single point of failure and also snuffs out what makes us human, actual, real diversity of people doing different things in different places and environments, under the guise of fraudulent diversity and diversification.
