Politics, as I like to say, is “the art of the impossible.” It is impossible even to imagine how, by a political process, any large modern nation state could devolve to the point where locals could have control of their own affairs. The vested interests for Large are too large. Big-league politicians, of any stripe, do not voluntarily part with their powers, whatever rhetorical roughage they may spew, and small interests will always be crushed or bought off — more often with lies than with money. This is why I concluded that with God all things are possible. They aren’t with men.
The limit of what we can do for ourselves through politics is seek ameliorations, none of which can possibly stick — unless something unforeseeable by any man happens.
Our foreseeable future is something like what “PRC” China is already achieving: using advanced surveillance technology to rank all citizens by obedience to the State’s commands, and arrest all those with failing grades. (Going offline and unplugging all appliances won’t hide you, as anyone with a techie son can learn; in our brave new world, even Jeff Bezos can be monitored.)
It is true, we still have some checks and balances in the West (semi-independent judiciary and the like), but note that they are all inherited from the distant past, and all are currently under unthinking attack from both Left and Right ends of the political spectrum. And while only one of those is demonstrably insane (guess which?) they routinely alternate in power.
