It is just a myth that you can lower the prices of housing by building more in the West Bank. The housing prices in the West Bank are maintained artificially low for Jews as the state subsidises those so heavily. In fact these subsidies (security, roads, telecommunications, schools, etc) cost very dearly to Israelis, which is the reason there are not enough public housing schemes in Israel within the green line. The housing prices in Israel would have most probably been lower NOT higher without the occupation.
