The minimum wage will be increased in Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Florida, Hawaii, Maine, Massachusetts, Michigan, Missouri, Montana, New Jersey, New York, Ohio, South Dakota, Vermont, and Washington to start 2017.
Wages will be increased by different amounts in different states, and sometimes by different amounts within those states.
New York state, for example, will see the minimum wage rise to $11 in New York City, $10 in downstate suburbs, and $9.70 elsewhere. Small businesses in the city will increase the wage to $10.50 for city employees, ABC station WABC-TV in New York reported.
Alvin Major, a New York City fast-food worker, and 51-year-old father of four, told The Associated Press that the increase in pay will make a difference in people's lives.
"The price of food has gone up. Rent has gone up. Everything has gone up," Major said. "This will make a difference for so many people."
The federal government has not raised the federal minimum wage in over seven years, when it was raised from $6.55 to $7.25 on July 24, 2009.
The Economic Policy Institute (EPI), a non-profit American think tank based in Washington, D.C. that "seeks to include the needs of low- and middle-income workers in economic policy discussions" through the publication of research and policy discussions, noted in a post published in July 2016 that the federal minimum wage, which is sets a floor at $7.25 per hour, would be much higher if it had kept up with a growing economy.
"As the top line in the graph shows, had the minimum wage kept pace with rising productivity [from 1968], it would be nearly $19 per hour today. Not $7.25," EPI said in the post.
Many business owners, however, oppose increasing the minimum wage on the grounds that in some cases it could make it hard for them to turn a profit.
Some restaurant owners may consider reducing portion sizes or charging for side dishes that were once included in the price of a meal to absorb the increase, Melissa Fleischut, president of the New York State Restaurant Association, told the AP about the decision.
Sanders referred to "huge progress" in the battle to raise the wage to $15, which could be read as an oblique reference to the changes taking place today across America.
"The #Fightfor15 started only 4 years ago. But huge progress has already been made because people everywhere see the justice of that idea," Sanders tweeted today.
