I dont understand why we have to go back to Christianity to survive.
Look at the east asians. They do fine without Christianity (japan/korea) or religion (china).
I see no decline in productivity or creativity when i take a look at my atheist friends.

Btw. In the last few years german scientist researched the topic of why different ethnicities integrate better or worst in the german society.
Until then most scientist believed it has solely to do with wealth and education of the parents.
After several studies that showed poor vietnamese children are actually much more successful in education then their peers (migrants and native germans) scientist believe that there must be more.
One explanation is Pierre Bourdieu's theory of mutual transformation of social, cultural and economical forms of capital as resources which parents can invest in their children.
Religion plays no relevant part in it.
