The Church has stopped acting like it believes what it teaches since "the Spirit of Vatican II". For example, if people receive Holy Communion in a manner that is not much different than lining up for a movie ticket, is it any wonder if faith in the Real Presence declines? The law of prayer is the law of belief; water down how the Church prays and faith will wither.  Would a non-Catholic visitor to Mass get the impression Catholics take belief in the Real Presence seriously if we looked at how Communion is distributed in an average parish?
