And this one, though it relies almost entirely on anecdotal evidence, really highlights what is just another form of the first world exploting Argentina's resources. It's not all that different from the US and Canadian mining companies extracting gold with polluting means, and making a fortune while Argentina gets little or nothing out of the deal.
In this case, the first world corporations get cheap labor, and Argentina is cheated of the tax revenue. It's actually more like piracy than a brain drain.
