The investment bankers aren't doing anything wrong, they just aren't doing enough. They are evaluating investments based on old world accounting principles and not accounting for today or the next 100 years.
Now you might say that the next 100 years is too long away, but when half of these companies are investing in superannuation (or pension investments) then you start to realise that they at least need to be thinking about the next 30 years (for me) and 50 years (for my children (to be)).
So their goal, from what I understand, it so do research and support on behalf of large investment firms to help them more accurately evaluate companies they are investing in. This puts flow on pressure onto the companies to make sure they aren't just brining in the cash, but are thinking about their long term thinking too.
As a bonus, this may encourage and foster long term thinking across the board in business, political and personal spheres in Australia and the world, which is a good thing.
