Brad helps them buy real estate from agents who usually cheat them. But from an outsider point of view, the Amish are not mocked. Their life-style is glorified and romanticized, as humble, rural people usually are in Hollywood comedy. They are shown as conservative, not fanatical.

The only violence is one gunshot and lots of pratfalls. Even in the big car chase, the joke is that none of the careening cars crashes. Outtakes of flubbed scenes are now popular during the credits of comedy. For Richer or Poorer varies this by showing parts of scenes that were cut from the finished film. Good thing, those edits, because this movie's 98-minute running time is already pushing the limits of the concept.
