It is especially common in cases where western companies are actively engaged in chasing the lowest possible production costs. An example would be in the manufacture of running shoes.
Usually this entails setting up a factory in a third world country and running it for a few years at subsistence level wages.
Eventually wage pressures force costs up (sometimes by only a very small amount) because strangely enough, people being people after all, the workers at these plants see them as simply the first step in a process to better their own situation.
This of course is at odds with The Brand, because they expect workers to sell them their labour at perpetual bargain basement prices which of doesn't happen.
This eventually leads the geniuses in charge of The Brand to up stumps and move in search of some new peasantry who are willing to man a factory at subsistence levels wages for them again.
The trouble is that the original factory is still there, as are the workers.
Also, quite often it just happens that the local government there (and perhaps fledgling business entrepreneurs) are more than willing to continue operating the factory making pretty much the exact same product that The Brand makes, but without the crippling overheads, which are usually made up of massive marketing budgets and executive remuneration packages.
It's a massive fail on behalf of business management, short term-ism trumping long term vision and burning them in the long run.
