Stranded passengers carry their luggages during a one-day nationwide strike in Buenos Aires

Stranded passengers carry their luggages during a one-day nationwide strike in Buenos Aires, March 31, 2015. Transport unions spearheading Tuesday’s strike are demanding the leftist government raise the minimum threshold on income tax as part of salary negotiations. The government said inflation was 24 percent in 2014, but private economists estimate it was about 35 percent. REUTERS/Enrique Marcarian
