The building industry is one of the most important for any nation, keeping them in jobs is one way of rating the economy. At least that's how I've evaluated it here. There is of course a flow on effect from such. If the building industry suffers it has a domino effect. If it succeeds then it has a very positive effect on the economy. Government sponsorships in these areas do help greatly from my little brain's knowledge.
I haven't seen your link yet but will tomorrow when I'm awake. lol
