I've been rewatching The Prisoner lately (protip-if watching use one of the alternate airing orders like 6 of 1 from The Prisoner Wikipedia page). It is amazing how much of what McGoohan was predicting in 1967 has come to pass.
He predicted things like the surveillance state, contact monitoring of people, cameras everywhere. The Algorithm predicting what you want to eat, buy, what you will do, where you will go. Fear, blatant propaganda, Rewriting of history, doctoring of videos. Everyone is a number. Drugs, bread and circuses and mindless pursuits to opiate the masses. Sham "democracy". Youth rebellion staged as pointless performance by the state. A world where you can trust no one and even those in charge are expendable and can't trust each other.
And the intersection of corporate control with state control. As you say, Leo McKern's Number Two laid it out in what I consider a pivotal scene (on the beach where the girl was swimming)--the two sides of the Cold War no longer matter. The amorphous Village Organization which is hinted to be very large and with tendrils in both NATO and Soviet governments is taking control. "The World as The Village"--illustrated perfectly by the end scenes of Number Two walking into the MP entrance of Parliament, where he is presumably a member, and Number 6's house door closing automatically like one in The Village.
He hasn't escaped, there's no escape, we are all in The Village now.
But even though 6 basically lost, I take heart watching his utter and total defiance at all times, especially as I refuse to be vaxxed.
