Wealth of a Nation

The Wealth of a Nation
How do you measure the wealth of a nation?
The answer: By the demand of real estate.
In good times, people want to upgrade their houses, there will be demand for 5-room flats and less for 3-room flats.

But now there are 10,000 excess 5-room units apartments and a greater demand for 3-room apartments.
People are downgrading.

Now you tell me, is this a sign of good time or bad time? Are the people prospering or are they getting poorer?
