Of course, some of the measures were "effective" against inflation. The Brazilian Central Bank fixed 1 BRL to worth 1 USD and lowered a lot of import fees, flooding Brazil with US goods. This helped put prices down at cost of our own industries.
Yeah, probably some of them (the economist and his buddies) thought the same and didn't give a shit. What happened them? Most of Brazilian industries got broke or were acquired under great circumstances by foreign companies. Long live plutocrats.
If you think that hyperinflation would solve itself without any of the policies adopted - fiscal tightening, privatization of troubled state owned companies, opening up the market, etc - I'd love to hear about your explanation for the current state of Venezuela.
