In the first century B.C.E., Julius Caesar implemented a series of redistributionist land reforms [1]. One component was a minimum-hold period to prevent the aristocrats from just going and buying it all back up again.
The re-concentration was absolutely foreseeable. Classical history is no longer fashionable in American elite education, so I get how this was overlooked by the bankers. But it points to a lack of a give-a-shit-factor which, in my agreement with you, does not confer responsibility, but does represent a massive missed opportunity.
