Australian farmers who get cranky about the government and threaten rallies or protest marches are whimps compared to their Argentine counterparts. Farmers in Argentina simply go on strike when they get fed up with the problems caused by governments.
This week, farmers in Argentina went on strike, refusing to deliver grain and livestock to markets. Relations between farmers and the government of President Cristina Fernandez reached a boiling point in 2008 when she imposed very high export taxes on grains and oilseeds during the 2007-08 international commodity price spike in an attempt to reduce exports and dampen domestic food prices. This time, the protest is about increases in land taxes. The dispute has attracted international attention because of the potential for an extended dispute to halt Argentinian soybean exports - Argentinian being one of the biggest global exporters.
Seems like the Argentinian farmers get a lot more serious about their protests than do their Australian counterparts!
