Because there are lags in the system? Because we are not doing enough? Do you always expect immediate feedback on everything you do? If that's the case I guess you never invest in anything because that's by definition a bet that it will make things better (or less worse) in the future.

So your proposal is to further delay making anyone pay for changes, because previous generations profited? So at the end of the chain (which will likely not be very long anymore) some generation will be completely screwed.
