"There is a bill before Congress that would boost America's minimum wage to $10.10 an hour," said former President Barack Obama. "It's easy to remember $10.10. ... It would lift people out of poverty right away; it would help millions more work their way out of poverty."
That bill never passed, which begs the question: It's been nine years, so what's keeping the federal minimum wage stagnant?
"It requires getting Congress to pass a minimum wage increase and a friendly president to sign it," said Tsedeye Gebreselassie, senior staff attorney at National Employment Law Project. "And so those things are not always a guarantee. ... It doesn't even even go up 10, 20, 30 cents to keep pace with inflation and cost of living. It's just totally flat."
"There's this myth that the majority of minimum wage workers are teenagers that are just working at the mall, and that's not true," Gebreselassie said. "... The vast majority of minimum wage workers are adults, not teens."
A University of Washington study found that a $15 minimum wage hike in Seattle hurt hourly workers by cutting back on their hours. Workers earned $125 less each month. Still, some experts say that study has flaws.
Without an increase in federal minimum wage, cities and states can still determine their hourly rate. So far, 29 states have higher rates than the federal minimum wage. And currently, there isn't a consensus in Congress to raise the minimum wage.
