Why Religion and Business should never mix?

yeah the founders of religion where poor. they didn't want to have to work for a living so wanted people to give them money, the only probelm was that people didn't want to give them money unless they where getting something out of it. so some one thought up the great idea of god and heaven and hell, give me money now and you will be rewarded in the afterlife for eternity don't give me money and gods gonna eat your babies and you'll burn in hell. think about it, zero overheads. one hundred percent profit its not like god want's a cut. thats good business in anyones language.
