For the first time in more than 6 years, the unemployment rate is below 6％. Over the past four and a half years, our businesses have created over 10 million new jobs. That is the longest uninterrupted stretch of private sector job creation in our history.
    But while our businesses are creating jobs at the fastest pace since the ’90s, the typical family hasn’t seen a raise since the ’90s. Folks are feeling as squeezed as ever. That’s why I’m going to keep pushing policies that will create more jobs faster and raise wages faster, policies like rebuilding our infrastructure, making sure women are paid fairly, and making it easier for young people to pay off their student loans.
    But one of the simplest and fastest ways to start helping folks get ahead is by raising the minimum wage. Right now, a worker on the federal minimum wage earns $7.25 an hour. It’s time to raise that to $10.10 an hour. Raising the federal minimum wage to ten dollars and ten cents an hour would benefit 28 million American workers.
    But Congress hasn’t voted to raise the minimum wage in seven years. Seven years. And when it got a vote earlier this year, Republicans flat-out voted "no". That’s why since the first time I asked Congress to give America a raise, 13 states, 21 cities and D.C. have gone around Congress to raise their workers’ wages. Five more states have minimum wage initiatives on the ballot next month. More companies are choosing to raise their workers’ wages. A recent survey shows that a majority of small business owners support a gradual increase to ten-ten an hour, too. And I’ve done what I can on my own by requiring federal contractors to pay their workers at least ten-ten an hour.
    On Friday, a coalition of citizens including business leaders, working moms, labor unions, and more than 65 mayors told Republicans in Congress to stop blocking a raise for millions of hard-working Americans. Because we believe that in America, nobody who works full-time should ever have to raise a family in poverty. And I’m going to keep up this fight until we win. Because America deserves a raise right now. And America should forever be a place where your hard work is rewarded.
