Suppose you owned a factory. You make world-class widgets as a step
in manufacturing a product for a market you've dominated years.
Suppose
someone else also makes widgets for their product in a different
market. Their widgets are aren't as good as yours, but they're made by
a different process at significantly less cost.
Do you adapt
their widget technology, maybe putting a little more expense in to
bring it up to your quality standards? Do you buy widgets from them?
Suppose the widgets are people?
