"Yet you don’t need SEEDS analysis to know that the British economy itself is at an advanced stage of disintegration."

"Put another way, very little of the world’s supposedly enormous wealth actually exists in any meaningful sense."

Citation overwhelmingly needed. His claim that the economy is disintegrating is supported by the argument that: "you know, just look around." But what we're looking around and seeing is wealth accumulating at the very top.

The mistake he's making is thinking that if most people aren't doing well, then nobody is doing well, that the 1% aren't even really rich because their wealth is all a fiction.

In fact, wealthy people are really, actually wealthy. They are unimaginably wealthy. It is literally beyond the author's imagination how wealthy they are, leading him to the truly absurd conclusion that they're not really even wealthy at all.

"Nobody could be that wealthy, could they?!" Yes, my dude. Yes, they actually can be that wealthy. Indeed, they actually are.
