According to that the S7 Krakow to Warsaw is never going to be built and neither is a single motorway going from north to south of the country.
Another 100billion needed.
Not really. Anybody who bought before 2007 is still quids in and in a major way. And based on what a flat in my building is currently on the market for (and what I know for a fact the owner will accept as a sale price), my place has still tripled in value since I bought it in 2000.
Not relevant for me or for anyone who bought after 2007.
I agree with the gist of what you are saying, but take inflation into account and the fact that a 50% fall=100% rise and with can become less rosy quite quickly. Prices are a feedback mechanism - falling prices makes prices fall.
