I know that this question might get closed, but I will try it, nevertheless. The reason why I am so interested in broad comparisons of historical situations with current ones, is because I believe that this is the single largest contribution the field of history can have to society.
My very broad question goes like this. What historical situation is comparable to what Europe is currently facing? By the current situation, I am particularly interested in the following qualities:
- Relatively large cultural differences between regions
- Mature and stable societies, that have not faced a crisis for a significant period of time (half a century in the current case)
- Being a significant power, but falling behind in the power-race
- Unsustainable in the long-term (aging societies), unless of course action is taken
If you believe that the question should get closed, please try to think of how I can ask a question to gain knowledge to better understand how Europe got into the current situation, and how it is likely to come out of it.
