even if so... the world is changing... social structures are changing... in the current times it is absolutly not important if the western cultures loose on "weight"
the nature will always find a balance... for everything
that we dont like this balance is also not important coz not we have to like it but our kids and what they would like to see we dont even ask or they dont even know yet
its like with the global warming... who does say that what we have now is normal and that how it developes in not normal?
maybe what we have now is not normal and we are developing to a normal state
(just an example)
