The people of Argentina are responsible, I'm sorry to say.
Step one: they voted in Cristina with majority of the votes because she promised them they were all going to get rich without actually doing the hard work.
Step two: they bought Cristina's BS when she said inflation was 8-9% and was going to remain at that level.
Step three: people went on strike and others supported them when they wanted 25% wage hike
Step four: companies were forced to increase the wages
Step five: companies realize they aren't charities and HAVE to make a profit to stay afloat so they pass the increase down to the premiums that people pay
Step six: step one to five is repeated in an endless cycle.
