The young people who would be good priests or ministers are chased out or harrassed until they leave. That leaves the perverts and non believers who eventually end up as non Christian Priests and ministers.
In some cases with Kali teachers, it is just the dumb who make it. They are apolitical until they become teachers and finally get a pay check besides one from BK or BIG MCD. Then they are told by the union that if not for the union, they would not have a regular paying job. So they must join the union and then vote for Davis, the Clintoon and the Goron. Of course they related to the Goron as one of their own, a real dumb sob, who passed as somewhat intelligent.
