This seems to me like saying that if the size of an inch shrinks, things measured in inches will too. I mean, for the sake of argument, maybe they will shrink and maybe they won't, but the choice of inches vs. cm can't affect that; it's extrinsic. This sounds very much like something I've read for decades, that it matters greatly if oil is denominated in dollars, and it's made no sense to me in all that time.

People complain about stagnating real wages, but I'm unaware of exponentially declining real wages, let alone the same happening to investments, as you mention, like 401(k)s. I don't see how the details matter; if there was significant wealth transfer from almost everybody, then it would be obvious.
I think you are saying that somehow, in emotional terms, the banks are a vampiric drain on the economy. But how are they doing that? If they somehow make money vanish, then doesn't that mean it isn't circulating and causing buying power and inflation? In which case how can it matter? If all the excess money is being hoarded by a tiny number of people who are not spending it, isn't that protecting us from the ravages of inflation? If I have a trillion dollar coin, regardless of where I got it, it's nothing, unless someone takes it seriously when I say "please make me 10 aircraft carriers".
The idea that financial institutions possess all wealth is so weird I'm not sure I can believe anyone believes it. You can look up how much they are worth, would you say that the published figures are misleading, or do you think that regular public financial companies and banks are vastly outweighed by other entities?
