What is vulture investor? If it is someone who "who buys up defaulted emerging market debt and presses authorities through various legal devices to press the country to pay more", then I think he or she is smart and the blame should go instead to the lousy legal system in the 'victim'(?) country.
Does the term also apply to business to business (b2b, as opposed to b2g)? I don't know. But even if it does, why should a vulture investor be condemned? I don't get it.
