What you say may be very true.
Many parts of Spain did rely on construction,howeve many did not.
Many of the construction workers that came to Spain may very move back home.( not like here they dont get freebies at our expence)
The house boom had to stop and thats what everyone was saying as supply was more than demand.
Perhaps that over supply in good areas may be taken up in many areas by those trapped here.
Many parts of the U.K relied to much in the finacial sector/housing easy money.
Town Centres die by the day.This along the British way of life as well.
Its all very sad
The difference is in the UK we dont have areas totally reliant on residential tourism.
