Exactly. Consider the business model -- A company tells you that you can outsource your IT department, buy it as a service, and pay the outsourcing company's overhead and significant profit margin, *and* save money. And the only way this could possibly work is if the outsourcing company goes to the LCC (least cost country) and hires the cheapest labor possible. This is justified in that all that IT stuff, it's all just following procedures, and anyone can do that.
And of course, this is a blatant falsehood, but executives of the victim company either (a) don't know that, (b) *want* to believe the scam, (like any good scam) or (c) don't care, because they intend to take their bonus and get the hell out of dodge.
So, outsourcing companies go into contracts *knowing* that cutover is going to be a Big Fail, and they have excuses prepared for when it happens. And a strategy (a brilliant strategy, really, executed by brilliant if unethical people) to string the con along as long as possible.
And just incidentally, the victim's attempts to train the workers that they are stuck with also fails in the long run, due to the nature of the business model. The business model breaks down if the workers are paid more than starvation wages, and workers with a bit of experience can easily get a higher paid job elsewhere (perhaps as a second or third level admin for a different outsourcing company) and they quit. And then you have a new person who doesn't know what a kernel is, and you have to train them up. And all you're doing is giving out free training. How noble of you.
But at least it's cheap. Oh, wait...
