I was giving an example of how the total expense cost/benefit calculation would work given a set of inputs. I don't know if the baseline is $400M labor and $200M vendor, which I clearly stated. I don't know what you are talking about with the 50% reduction in labor, since that was not an assumption I used (I used the 30% reduction referenced in the article).
I'm not trying to confuse the issue, but rather clarify how comparing the % increase in one cost item to a % decrease in another item does give an accurate picture of the net financial difference. You need to apply those percentages to the baseline values of each. Again, this is gradeschool level mathematics I'm explaining, which I had to do because of false conclusions that were made from the earnings announcement articles.
