Fear of reality is the main recruiting tool that religion remaining in its box of tricks and illusions.
However more and more people have ceased to fear the idea that death is the end, even religious people find the traditional idea of heaven to be silly and the threat of Hell despicable.
Mainstream churches are complaining that their congregations are dying off and young people are not coming in to replace the oldies. Though people in their fifties and sixties will claim a belief in god, most only attend church for weddings and funerals and christenings are becoming rarer as parents decide to leave baptism for the children to decide on when they get older.
Religion is fading in the west (except for in parts of the USA) because desperation and poverty are fading in the west except for in the USA, it is no coincidence that people turn to god when there is no medical and welfare system to turn to and where losing your job can mean your children may die from a treatable illness but you cannot afford to pay for the drugs.
