I agree some of the comments in FT are very interesting.

I'm not saying that productivity is going up, it's in fact going down, as the article says -3.1 variation GDP 2008-2009. But the ratio of unemployment/varGDP is very different to other countries because of the additional unemployment from construction industry, which is the suspicious indicator used by the author.

In any case I personally agree with some of the comments in the FT article saying that Spanish government may artificially modify some figures.
