In our Capitalist America we really do have a form of slavery in states with really low minimum wages for jobs. Talk to any minimum wage worker trying to survive off that income, it's next to impossible. They are being paid slave wages. My wife has been a minimum wage worker for decades. When I married her she was homeless. She had a full time job, but slept on the streets because she didn't make enough money to pay rent or anything. She had more debt than income. Her debt to income ratio was like at 80%.
In a way she was being paid slave wages as a fast food worker and this could be called a form of slavery that fast food joints often use on their workers to keep them working. It is exploitation at a massive scale in the USA. More states should follow California and raise wages for fast food workers, end the barbaric slave wages that seem to put so many fast food workers in a form of slaverly they can't seem to get out of. Why they even bother to show up for work if the job pays so little that it seems they are working for free and can't pay their bills?
