The last 50 years has seen a drastic decline the number of religious people in western europe. In that timeframe, we have also seen:

-drastic economic growth among the general population
-women accepted as equals instead of lesser people
-pre-marital sex is now the norm and fully accepted
-gays are more accepted than ever before
-positions of power are no longer reserved for white, hetrosexual males
-most blasphemy laws and other such restrictions of free speech have finally been removed
-democracy is spread around the world
-universal rights and benefits like healthcare
-abortion is completely legal and accepted
-violence is no longer an accepted form of child-rearing
-neither is violence in marriage accepted

I could go on all day, but I believe this is enough for now.
