Oh poor beautiful Seville, how terrible for everybody.
I think the anger is growing out there, and things could turn out unpleasantly, but I do hope not. Mass unemployment is one of the factors that can turn people towards extremist parties, as history shows us rather uncomfortably clearly.
When I was walking north from Seville, the main emotion I encountered seemed to be resignation rather than anger. However, the latest revelations about corruption and insensitivity near the very top (literally at the top if you count the king going big game hunting) may turn resignation into anger. The indignados and the desahuciados are growing in numbers.
¡qué vergüenza! as they say.
