If God wanted us to bend over he’d put diamonds on the floor.

In Rivers’s punchline, the mock-theological premise (“If God wanted…”) is used to justify a very worldly impulse: refusing to stoop for anything unless it’s materially rewarding. The joke hinges on the contrast between pious language and blunt consumer desire, a hallmark of Rivers’s comedy about status, money, and the indignities of everyday life—especially for women expected to be accommodating or self-effacing. Read more broadly, it satirizes rationalizations people invent to avoid inconvenience, and it skewers the idea that hardship is inherently virtuous. The line’s sting comes from treating luxury (diamonds) as the only acceptable reason to humble oneself.
