Num post do Blasfémias, encontrei esta notícia do Financial Times.
"Other countries are less fortunate. Take Portugal, Italy, Greece and Spain, sometimes described as the Pigs. It is a pejorative moniker but one with much truth.
Eight years ago, Pigs really did fly. Their economies soared after joining the eurozone. Interest rates fell to historical lows – and were often negative in real terms. A credit boom followed, just as night follows day. Wages rose, debt levels ballooned, as did house prices and consumption. Now the Pigs are falling back to earth."
