The stark divergence between 2011 and 2013 forecasts for Portugal's economy show the need for better terms on Portugal's EU loans. The 2011 forecasts of EU lenders estimated a much lower level of contraction in the economy and unemployment. In 2011 the lenders estimate was for a economic contraction of a combined 4% in 2011 and 2012 and returning to growth in 2013, with unemployment peaking at 13%. The forecasts in 2013 estimate the economic contraction at 7% for 2011-2013, with unemployment reaching 17.3%. Portuguese government officials say they overestimated tax revenues and underestimated the payouts for social benefits to the unemployed. Prime minister Coelho is criticized for increasing taxes and making spending cuts blindly. He faces angry protestors singing the anthem of Portugal's revolution against the dictatorship in 1974- "Grandola, Vila Morena."
