(CNN)The schoolchildren who faced water hoses and police dogs in Birmingham gave the civil rights movement one of its most iconic victories. But a new generation of activists has arisen in the city with another message:
The Fight for $15 takes on the 'Jim Crow economy'
The "for colored only" signs may be gone, but the "Jim Crow economy" remains.
That is the thrust of a lawsuit linking a three-year battle to raise the city's minimum wage with Alabama's ugly racist heritage. Oral arguments were heard in federal court on Friday after a coalition of civil rights groups sued to preserve an attempt by Birmingham's majority black government to raise the city's minimum wage.
The suit is the latest skirmish in a national battle over the minimum wage. At least 21 states and DC have raised their minimum wages above the federal level of $7.25 an hour in the last four years, and at least 41 localities have adopted wages above their state minimums. Many have done so because of protests by Fight for $15, a workers' movement that seeks to raise the minimum to $15 an hour.
Legislatures in at least 24 states, including Alabama, have responded by passing "pre-emption bills" that either abolish or roll back those increases. What's different in Birmingham is the racial dimension of its minimum wage battle -- and the massive implications of a workers' movement gaining a victory in a Southern city.
Birmingham became the first city in the South to try to raise the minimum wage for anyone employed within its city limits. The primary beneficiaries of the raise would have been fast-food and retail workers.
Alabama lawmakers responded by passing a law that abolished the wage increase. Every Alabama lawmaker who voted against the raise was white, according to the lawsuit.
A coalition of groups that included Fight for $15 activists sued the state in 2016, saying passage of the law was tainted by "racial animus" and relied on a state constitution that still has explicit language geared toward putting blacks in their place.
"They treated Birmingham like it had whistled at a white woman," says Scott Douglas, executive director of Greater Birmingham Ministries, one of the plaintiffs in the suit. "It was like an insult: 'How dare you raise your own minimum wage without our say-so.''
CNN tried to reach at least four Alabama lawmakers who voted to overturn Birmingham's wage increase, including some of the most outspoken opponents. None responded. Alabama's attorney general's office, though, made the state's position clear in a brief filed with the 11th US Circuit Court of Appeals. The court is hearing an appeal by the plaintiffs after a federal judge dismissed their lawsuit. A decision is not expected for months.
The brief said Alabama lawmakers were motivated in part by studies that suggest minimum wage increases cause more unemployment and don't reduce poverty. It said the state was well within its rights to oversee the economic regulations of its cities, and pointed out that numerous states had already passed similar laws preventing localities from enacting their own minimum wage laws.
"To get around this, the appellants asserted a dizzying array of legal theories casting Alabama's minimum-wage law as state-sponsored racial discrimination," the brief said.
Linking a minimum wage battle in Birmingham to water hoses and attack dogs may seem far-fetched, almost obscene. But the famed 1963 civil rights campaign was spawned by economic concerns in the city's black community as well. The initial goal of the campaign was to desegregate downtown stores for black shoppers and persuade merchants to hire black sales clerks.
The Rev. Martin Luther King Jr. often noted that racism and economic exploitation are intertwined.
"What does it profit a man to be able to eat at an integrated lunch counter if he doesn't have money to buy a hamburger?" King said.
Blacks in Birmingham still have trouble buying a hamburger, the plaintiffs argue. According to their suit, the city is about 74% black; 32% of its black residents earn below the federal poverty line; and the average black resident earns about $16,000 a year.
Poverty in the city's black community has spilled into the closest thing to sacred ground in Birmingham -- a park dedicated to the 1963 campaign.
Kelly Ingram Park was the four-acre epicenter of the 1963 protests. It's where black school children were lashed with water hoses. It's now a civil rights monument, ringed with sculptures of King, statues of demonstrators facing off against lunging attack dogs, and benches adorned with photos of civil rights martyrs.
Homeless black men also populate the park. They shuffle through the manicured grounds with soiled clothing and matted hair like zombies. Some mutter to themselves, heads cast down. Others sleep on park benches. One panhandler with a ZZ Top silver beard and a toothless smile approached strangers on a recent day asking, "Gotta dollar?"
Across the street, Antoin Adams, a young man with gold teeth, leaned his lanky frame against a civil rights museum facing the park. He's not there to reflect on the past; he's trying to make some new history.
Adams, 24, is one of the plaintiffs in the lawsuit. At the time he joined the suit, he was making $7.25 an hour at Hardee's and lived in Section 8 housing. His job came without health benefits, but he was making too much for Medicaid. Alabama refused to expand Medicaid under Obamacare, leaving him to call 911 for free breathing treatments for his chronic asthma.
Adams said he couldn't afford the cost of an inhaler.
"I know I need it for my asthma, but the bills need to be paid. It makes you kind of think of giving up, but you can't. Life goes on."
Adams is joined by Michelle Jones, a Fight for $15 activist. Bubbly with a big smile, the 28-year-old said she could barely afford to eat after paying her bills and bus fare on her $7.25 an hour wage at McDonald's.
"Two ham sandwiches a day -- one in the morning and one at night," she said when asked to describe her diet. "Sometimes it's just crackers and noodles."
Jones and Adams swapped stories about the grim choices needed to make a living on minimum wage: Do you pay the water bill or gas bill? When you're in pain, how long do you wait before paying for a doctor's visit? How do you get to work on time when the buses you rely on often break down?
Before their conversation ended, they mentioned a startling detail. They said they'd sought out black veterans of the 1963 campaign to get advice and inspiration. Instead they got shrugs.
"They'll be like, 'It ain't going to happen. You're fighting for nothing,''' Adams said. "I thought older people would motivate us. I never thought it would be like that."
Their pessimism may be understandable because of a geographic reality: It's difficult to organize any workers' movement in the South.
The region is the most hostile in the nation to workers' rights. Every Southern state has "right-to-work" laws that make it easy for companies to fire employees -- and difficult for unions to organize. Only five states have no state minimum wage. All five are in the South -- including Alabama.
This Southern hostility to workers isn't a coincidence. It's tradition. Since the late 19th century, many Southern states have embraced a similar economic approach, some historians say: slash taxes to attract corporations, pass laws that weaken unions and pull back on investing in public services like infrastructure and public schools.
Some groups are starting to rebel against this economic approach. Public school teachers in red states like West Virginia and Oklahoma have staged walkouts and protests over low pay and funding cuts, placing many state lawmakers on the defensive.
Southern political leaders, though, traditionally have been hostile to any measures -- guaranteed health care, unemployment benefits, minimum wage laws -- that would make workers less dependent on employers, these historians say.
Some call this economic approach "Southernomics." After the Birmingham lawsuit was filed, one woman described it as a fight against the "Jim Crow economy."
"The days of a Jim Crow economy should be long gone," said Christine Owens, executive director of the National Employment Law Project, a nonprofit group that promotes policies to protect low-wage workers and the unemployed.
"But sadly, the refusal of Alabama's legislature to allow Birmingham to meet local needs through appropriate local measures signals the past persists."
