They
Will
Never
EVER
Voluntarily take accountability for their actions and repair the damage they've caused.
The bosses need to be locked up, and their PERSONAL assets liquidised to pay for the damage they've caused, and to compensate all of the bill-payers who have been paying for proper sewage disposal that never happened. Then their companies need to be dissolved, and until we're able to abolish the state, too, all be nationalised.
Of course Keith (or whichever institutional puppet comes next) is just going to keep giving them slaps on the wrist while patting them on the back and congratulating them on their record profits, but still, it's nice to imagine..
