You are essentially stopping the flow of foreign capital into the country on an economy with extreme inflation and unemployment rate.
People don't need beef. Trying to make an easily substituted luxury good affordable that is bringing a significant portion of all foreign capital into the country seems short sighted, to say the least.
Welcome to Kirschnerism...
I love Argentina, it's such a great place to visit, and is still hopefully the place I would retire, but politically I fear it might be headed towards Venezuela.
Many people does not think in terms of 'flow of foreign capital', but in 'greedy exporters are hiking prices to get rich'. So forbidding exports and fixing prices look good to them (especially with propaganda support), while macroeconomic effects will go unnoticed.
(from experience in Russia, but Argentina looks quite similar in political structure)
I agree technically speaking, but try telling that to the average Argentinian ;)
Now I know who wrote it! Thank you!
