The Efficacy Prayer

If prayer actually worked in an empowering way, the powerful would stop at nothing to keep the powerless from doing it.  The poor are encouraged by the establishment to pray for the improvement of their circumstances but not to vote for people who could do so.  If prayer empowered the powerless would be brainwashed into not doing it.  Maybe they would be told prayer was harmful or the rich got the answers they prayed for.
