It is possible they are making a mistake and completely missing a great money saving opportunity, but I would not bet on it.
There very well could be new opportunities for labor arbitrage that can be taken advantage of by many businesses, and if so, it will be evidenced by the success of companies that take advantage of it. But it might take some time.
But it is not a new idea, and is certainly one that has already been tried, and so if certain companies are not taking advantage of lower labor costs elsewhere, then it is prudent to assume there is a good reason.
We live in a different world than a few years ago.
I hope I'm wrong because I'm benefiting from geographical effects and I have no delusions that I'm smarter than almost 6 billion people.
