This is the key factor that was missed in the above analysis. The reliance on construction employment cannot be ignored. If you stop building, yes on the face of it supply will be restricted so demand will go up leading to increasing prices. However, the economy has been kept in a spiral for the last number of years of house construction fuelling employment fuelling house buying fuelling house construction. Slow construction, you slow employment and so slow demand too.
Where I'd differ is that whether the foreign builders will return home. On the contrary, the developers will probably increase the numbers that they can shaft on agreed terms and conditions, instead letting go the workers that want and insist on the agreed rates of pay. They'll be allowed to do this by the Government with the support of IBEC/ISME/Every media organisation - like they have the last number of years.
