It is certainly true that there has been a dramatic increase in the number of highly paid people in finance over the last generation. Recent studies reveal that most of the increase has resulted from an increase in the value of assets under management. (The percentage of assets that financiers take in fees has remained roughly constant.) Perhaps some policy could be found that would reduce these fees but the beneficiaries would be the owners of financial assets – a group that consists mainly of very wealthy people.
I hope you can fight through the FT gate here, the piece is interesting throughout.
