Cultural and social issues on east and west

Firstly, what problems/issues (specifically cultural and social) that the Western world has to go through.
Secondly, what cultural and social problems does the Eastern world (any country including and east of Turkey) have to go through.
Do both sides of the world go through similar problems? Or are they different?
And more importantly, do you think each side can learn something from the other?. And what do you think the West can teach the East? And what can the East teach the West?
