There prevails anyway. With a residential tour, loosely 50, 100 or more people are frolic.
In Frankfurt am Main currently live about 750,000 people. If suddenly 1 million people would go there, the city would have to be more than doubling. This is actually impossible within a short time. Good possible to live in 2070 times 1.75 million people in Frankfurt am Main ...
Then there would be the possibility that these 1 million people z. B. refugees would be, or other people who want to live on the street voluntarily. Theoretically, these 1 million people could just live on the street. But that would provide chaos ...
Where should she have 'pull'? On the streetE?
They could only want to 'want', but that would not work because there is not enough living space (work, roads, jobs, shops, water, etc.)!
No idea how big the fluctuation is in a 600K big city, but prices and rents for the (a few) free apartments would rise very much and it would not come to 1 million!
