SFD/MFU

Shit Flows Down, Money Flows Up

How things work. The rich get richer and the poor get the shaft.

A company goes bankrupt and everyone loses their pensions while the CEO and upper management get million dollar bonuses.

"Yeah, that's how it works, SFD/MFU."

How Tony Soprano describes the mafia. "Shit flows down, money flows up."
