Sara Huertas still lives with her parents at age 30 because her supply teacher salary doesn't pay enough for her to rent a home in Madrid with her partner. "We looked south of Madrid, because it's impossible in the capital, but still we got nothing," Huertas said at a recent housing protest. "They need to do the right thing: reduce house prices and increase wages." Huertas is among Spaniards who feel they aren't reaping the benefits of Europe's fastest-growing economy. Instead she's struggling to put a roof over her head.
