BULLshit.

Most restaurant owners I know have decent houses, vehicles paid for, regular vacations, etc. Often they're spouses who can alternate management shifts so they have time with the children without daycare costs or they've got a shift manager and aren't even present in the workplace half the week.

Many of the the workers can't afford a vehicle, are stuck in a bad rent-cycle (often of dodgy places) and vacations... ha! Often they're working multiple jobs to get the hours needed to pay the bills, and if they have kids they're constantly fighting to balance their hours with whatever discount child-support times they can find. 

The owners often aren't rich fat-cats eating caviar and shorting coke off of hookers, but they're still way ahead of their employees in terms of quality-of-life.
