Portugal's disgruntled Facebook generation, inspired by a pop song, marched in a dozen cities today to vent its frustration at grim career prospects amid an acute economic crisis that shows no sign of abating.
Some 30,000 people, mostly in their 20s and 30s, crammed into Lisbon's main downtown avenue, called onto the streets by a social media campaign that harnessed a broad sense of disaffection.
Local media reported thousands more attended simultaneous protests at 10 other cities nationwide.
A banner at the front of the Lisbon march said: "Our country is in dire straits" while another said: "We are the future."
The Lisbon march was festive and raucous, featuring brass bands, drum combos and small children with balloons. Middle-aged parents also turned out.
Portugal, western Europe's poorest country, is producing the best-qualified generation in its history, thanks to big investments in education.
But after a decade of feeble economic growth and a huge debt burden that has forced the government to enact crippling austerity measures, Portugal's economy can't deliver the opportunities that trained young people are seeking.
The jobless rate stands at a record 11.2%, and half the unemployed are under 35. In the third quarter of last year, 68,500 college graduates were idle - a 6.5% increase on the same quarter the previous year, according to the National Statistics Institute.
Like Greece and Ireland, other debt-heavy European countries, analysts say Portugal is on the verge of needing an international bailout that would prevent its financial collapse but doom it to more years of recession.
"People's well-being has taken second place to financial matters," said Luis Santos, a 28-year-old out of work since graduating from Lisbon University three years ago.
"It's hard to come across anyone who's happy about their prospects," he said.
Portugal's youth is not just angry at unemployment but at "underemployment" - low paid, dead-end jobs beneath their levels of qualification - which leaves them stuck at home with their parents into their 30s.
Goncalo Montenegro, 45, was at the Lisbon march with his 14-year-old son. He works as a salesman but said he is worried about his son's future.
"We're passing on this mess and our debt to the next generation," he said. "We have to find a different path."
Four graduates in their 20s were inspired to organise the unprecedented protests after a pop song struck a chord with their despairing generation.
The song, called What a fool I am by Portuguese band Deolinda, was an unexpected hit in January, even though it hadn't been released yet. An amateur video of a concert performance of the song posted on YouTube went viral as it set a generation's simmering grievances to music.
The song's lyrics - including the lines "I can't go on like this/This situation's dragged on for too long" - built into a battle cry.
Joao Labrincha, a 27-year-old unemployed graduate from Coimbra University, said he and three friends took a spontaneous decision to organise the marches after seeing the video.
"We realised that lots of people are unhappy. It wasn't just us," Labrincha said. Within weeks, thousands had signed up to their Facebook page.
The protest's manifesto said it was not targeting the country's embattled government but hoped to make people aware they have to pull together to change the country's course.
After contracting in 2009, Portugal is forecast to record a double-dip recession this year.
Portugal's current economic plight stems from its inability to generate wealth while amassing massive public and private debt to finance its western European lifestyle.
