Do you mean in terms of shareholders being pension providers etc? Agreed that makes any and all industrial nationalisation difficult now but far from impossible.
I’m sick of seeing things like what the Thames Water CEO has come out and said, that in order to carry out the improvement works needed to maintain a decent level of service, bills will need to be increased. Nope, bills will need to be increased in order to carry out the works AND keep the shareholders happy/profiting.
