Wages for tipped workers, and wages for non-tipped workers.
Minimum wage for tipped employees has been frozen at $2.13 per hour since 1996.
The Bureau of Labor Statistics reports that waitstaff have a median income of $8.03 per hour, including tips.
Their non-tipped counterparts don't do much better, with hosts and hostesses averaging around $8.42 per hour.
If those workers are trying to support a family of three, they'd need to earn at least $8.80 to get above the federal poverty line.
