Because of the declining population...

I don't think there's a direct relationship between population change and any of this stuff. How many IPOs did Algeria have last year...or Egypt...or Nigeria? All experienced tremendous population growth. Israel, on the other hand, grows slowly but produces enormous technological advances.

The things to look at are technological changes and the ability of institutions to adjust. Remember the Luddites who predicted disaster as mechanization displaced agricultural workers? There's no inherent reason why technological advances cannot reduce the costs of goods and services to the point where very few workers are needed to provide both to everyone...but can we devise a society which will accomodate those changes?

There IS a direct relationship here. German social and Health systems are Bankrupt because of it. This is not conjecture, it is happening NOW. They don't have the population to pay into the system anymore. Their ratio now is 2:1. Soon it will less than 1:1. It doesn't take a mthematical genius to determine that this won't work.
Why do you think the EU is so determined to bring all these countries into the fold? There will be a centralised Tax system and the big 3 want to control them and benefit from the new members prosperity. Without those additions Germany could not sustain itself.
Of course there will be other problems, but those are 10-15 years down the road.
