GDP computed on the expenditure basis GDP (Y) is the sum of consumption (C), investment (I), government expenditures (G) and net exports (X − M). Y = C + I + G + (X − M).
In Argentine G is shrinking and so is C while I probably is stagnant. Therefore, at least in the short term, a recovery has to come from E or to be more exact, the primary sector with special relevance for the agricultural sector.
But with the recent influx of financial capital into the country the peso has appreciated substantially making its agricultural products uncompetitive in the international markets and its farmers poorer.
The most effective solution would be a devaluation of the peso, something that would not be possible to blame the previous governments for.
