Mind you it's a lot worse here in the EU thanks to Frau Merkel.
Gilsan, while I am not optimistic about obtaining a considered response from you, I'd be curious to know what this diagram suggests about the German population:
That is what is called a "population pyramid". It is usually called that because for most countries, it tends to be fatter on the bottom and skinnier at the top. It shows the distribution of population by age. Germany's population pyramid, like several other Western countries, is not pyramid shaped. It's not even rectangular shaped. It is very skinny at the bottom compared to higher ages.
Now, you may notice that the peak population age in Germany is in the 50-54 age bracket - which is almost DOUBLE the size of the 10-14 age bracket.
Given that population distribution, what would you predict is going to happen to Germany ten years from now when the size of the population entering retirement age is double the size of the population entering the job market?
If Germany's population pyramid stays that shape (i.e. the lines move up with the "skinny at the bottom" trend continuing), then the German economy is going to crash.
While this may not be obvious to you, or many others here, people give birth to babies. They do not give birth to young adults.
In the face of an obviously-developing economic crisis implied by the German population pyramid, Germany has two stark choices, either:
(a) figure out how to give birth to young adults - A LOT OF THEM, or
(b) get them from somewhere else.
Which of those alternatives seems like a better plan?
