Actually, when I was in Barcelona, all of the drudge work (street cleaning, vending, housekeeping) was done by the Ecuadorians and Peruvians. Lots of Filipinos in the hospitality industry over there as well. Then you have the African girls plying their tricks on the Ramblas.
Lots of South Americans are going to Italy as well. This is especially true if they can prove at least one Italian grandparent, which all but entitles them to citizenship (lots of Italians settled in South America, you may recall). Lots of Ecuadorians working on construction sites in Milan and Rome until the recent crash in the real estate market over there.
Sudacas? Had to look that one up
