What percentage of that $6B?
would have gone for employees in the US otherwise?
That would be, let's see, ummm, carry the 9, factor in pi to 29 decimal places, square it to cancel out the imaginary factor, square root of the speed of light in green jello...
Um, some magic happens here...
This part is left as an exercise...
There is a neat proof of this bit, but it won't fit in the margin...
2x + 3y +z = -3
Unfortunately, the derivation for this step requires understanding material we will be exploring later in the semester. For now, you just have to take my word for it...
x = sqrt(x) ^ 2
Ah, here it is...
Savings is defined as the difference between what you would have spent and what you did spend. So we have
$6B is the amount of money that would have been spent on US employees but wasn't, less the amount spent outsourcing to India.
The percentage of the $6B that would have gone to US labor is
(($6B + {cost of outsourcing}) / $6B ) * 100
So, taking the limit as the cost of outsouricng approaches zero, we get 100%. In real life, though, the cost of outsourcing is significantly non-zero. In which case, the percentage is higher than 100%.
For example, if it cost $3B to outsource to India, in order to get $6B in savings, we would have to cut $9B in US labor costs. So what percentage of the $6B would have been used to pay for US labor?
((6B + 3B) /6B) * 100
150%.
OK, so let's try to be fair - some of that $3B is going to finance computers for those guys in India to do the work on. Which will help increase the market for computers that are made in - no, wait, they aren't made in the US, we outsourced that already.
