This sort of phenomenon is a natural effect of globalization. A century ago, the world contained wealthy advanced nations, developing nations, and lots of "backward" nations which lacked modern industries and hence had a relatively low standard of living. However, this was somewhat compensated for by a low cost of living. Someone might only earn a dollar or two a day, but food was cheap and life was OK.
Enter globalization: the inevitable outcome of free-market, free-trade economics plus cheap ubiquitous transport. Within a few decades, the world became one single marketplace and - as we in the wealthier nations have seen to our cost - jobs began "finding their own level", that is being exported to the cheapest countries.
Not satisfied with that, bosses and shareholders wanted to bring in cheap labour to do those relatively few jobs that couldn't be done "at long range". Obvious examples are construction, health care, personal service of all kinds, and to some extent expensive specialities like law. (Not many lawyers in India have US bar qualifications, and even if they had they couldn't very well show up in a US court).
After the first irrational exuberance for outsourcing skilled jobs (like IT) to cheaper countries, even the most thick-headed of PHBs are now coming to recognize that outsourcing of this kind doesn't usually work too well. No matter how good the workers are, the communication problems (and often cultural discrepancies) are just too great. Hence the increasing eagerness to import cheap (but well qualified and skilled) labour to do those jobs under direct (not to say oppressively close) supervision.
Unfortunately, citizens of nations like the USA get it coming and going: the government taxes them heavily in order to provide services in a "first world" manner, while allowing business to export jobs to "third world" nations (or bring their workers to the USA to work there). This is a classic "wealth pump" which systematically sucks up wealth and transfers it to the rich.
Ironically, globalization looks set to be pretty much complete and settled in, just in time for the cheap oil that made it possible to run out. Then we'll all have to face the expense and disruption of reverting to relative economic independence within our own countries.
