As I see it, government is centripetal, in that it organizes and centralizes the social organism. While economics is centrifugal, as value is distributed across networks in larger equilibrium, without centralized definition.
Basically the relationship between nodes and networks, organisms and ecosystems. Companies exist as organisms, with their own centripetal focus on surviving in the larger ecosystem. Governments do function as social corporations, within historical and geographic ecosystems, not just economic and monetary ones.
Money functions as an interface between the ecosystem and the organism. Like air and water are mediums in which organisms function, that define the ecosystem. When those controlling these necessary aspects of the system use their power to deprive and monopolize the resources, either they kill off the larger system, like drought reduces life, which gave them power and influence in the first place, or they generate blowback, where the system, the other organisms in the ecosystem, take away their power.
Monarchy is a good example, in that it was essentially private government, but as those to whom the reins were passed, lacked the vision to understand what their role in the larger system entailed, they were usurped, eventually to the point the entire institution came to be viewed as antiquated and the role of government came to be treated as a public utility.
Currently banking appears to be having its own, "Let them eat cake." moment.
Now government, as the executive and regulatory function of society, is analogous to the central nervous system, while money and banking, as the value distribution system, is analogous to blood and the circulation system. So government and banking serve opposing functions in society, as one is centripetal, while the other is centrifugal.
Consequently banking can't be a direct function of government, anymore than government can become an appendage of banking, as it would seem is the situation today.
The problem of democracy is that the opportunity for long term vision and planning is constantly being interrupted by elections, the short term promises required to win them and the constant turnover of leadership. Leaving government at the mercy of the banking system and hollowed out, with puppets deciding which countries to invade, but not whether invading other countries is a wise use of resources.
Where it goes from here, time will tell. Though the impending shortages of fossil fuels will likely result in a breakdown of current power structures, leaving leaner and meaner ones in control.
Without the ups and downs, it's a flatline anyway.
