LONDON — For almost two years, Nicki Edwards has been looking for work — any type of work.

She is 19 years old, well-spoken and self-possessed. But like many young people in Britain, she could not afford to remain at her university, making it impossible to find a job. London’s youth riots last summer have closed even more doors to people like her.

“If you are not working, in training or in college, you might as well be a thief — employers just do not take you seriously,” Ms. Edwards said. “At some point, you just say, ‘I’m stuck and I will never find a job.’ ”

Perhaps the most debilitating consequence of the euro zone’s economic downturn and its debt-driven austerity crusade has been the soaring rate of youth unemployment. Spain’s jobless rate for people ages 16 to 24 is approaching 50 percent. Greece’s is 48 percent, and Portugal’s and Italy’s, 30 percent. Here in Britain, the rate is 22.3 percent, the highest since such data began being collected in 1992. (The comparable rate for Americans is 18 percent.)

The lack of opportunity is feeding a mounting alienation and anger among young people across Europe — animus that threatens to poison the aspirations of a generation and has already served as a wellspring for a number of violent protests in European cities from Athens to London. And new economic data on Wednesday, showing much of Europe in the doldrums or recession, does little to bolster hopes for a better jobs picture anytime soon.
