inverse-proportion of business-minding

Refers to a "it would be humorous if it weren't serious" social truth: if someone habitually sticks his nose in where it doesn't belong, his OWN life is usually gonna be in total shambles --- in other words, he's so busy minding OTHER people's business that he doesn't have any time or energy left to mind his OWN business properly!

A good way to determine if a self-proclaimed "vigilante of morality/diligence" is truly “caring ‘n’ helpful” is to view da overall status of da loudmouth's OWN life --- if he’s merely a grumpy loner whom da locals mostly avoid, then he's probably just a classic example of da inverse-proportion of business-minding; he merely wants to "feel important for five minutes". Reminds me of dat arrogantly-righteous and absurdly-overzealous young lawyer I once saw on TV, and who was actually bringing criminal charges against teenagers who were merely having intimate relationships. Many of da teens --- and even some of da parents, much as they themselves disapproved of pre-marital sex --- felt dat da sniffy-Puritan attorney was grossly overstepping his bounds. Yet when da interviewer asked him da most obvious question imaginable --- whether HE HIMSELF had ever sought sex from a girl during his OWN teenage years --- he suddenly got snootily offensive, and huffily monotoned back with, "Sir --- I will be compelled to terminate da interview if this line of questioning is pursued." HA --- looks like da only real reason for his being such a litigious a**h**e was dat either HE HIMSELF was privately embroiled in some paternity suit and/or sexual-misconduct allegations and so he wished to appear fiercely-moralistic to seem innocent of any wrongdoing, or else he was merely JEALOUS of da hot young studs in da neighborhood who were "getting lucky" with all of those "cute 'n' juicies" sweet-sixteens!
