Catholic Europe has lots of those roadside shrines, dedicated to saints of course. And lots of folklore and belief in other beings coexisted alongside that. What killed it was materielism, where man seperating himself from the cosmos and standing outside it, measuring it, cataloging it, manipulating it reduced it from being to object. The Romantic movement of the 1800's-1900's pushed back against materialism, and sought to reintegrate man but materialism was already becoming atheist materialism and man's consciousness got stuck. Seperated but unable to re integrate without a spiritual view of the cosmos and a correct understanding of God and what His desires are.
Personally, I think that this problem is only going to be overcome at the individual level, each person must take responsibility for his own beliefs and not hadn over decision and understanding to an outside church or book.
