And, of course, it's debatable whether or not 'nationalisation' by a neoliberal, consolidator state is the answer. Asset manager society has developed precisely because the ideology of the main UK political parties has willed it, and they will clearly only re-nationalise as part of the de-risking 'contract' with the asset manager corporations. It's no coincidence that this whole sector of the economy remains beyond regulation and is 'overseen' by toothless bodies that have themselves been deliberately hollowed out.
I think
Nine Bob Note neatly sums up above how the blue/red tories would see any 're-nationalisation'; take on the debt, hold for a short while then, having de-risked, sell on to another set of asset manager criminals. Same old, same old; privatise the gains and socialise the losses.
