I also have to say in Spain almost 2/3 of PIB is generated by services sector (Turism is a big thing here) and the rest by manufacturing industries and primary sector (Fishing and agriculture) and in services sector the productivity is minor than in the other sector because you can't improve your production with technichal changes, you have to hire more people with the same productivity. Pd: If you see the stats is not really a problem. The differences aren't so big.
