Clearly most people don't consider forced labor slavery in a prison environment. At least not in California or any of the other states that allow it.
I voted against it because I think they are plenty of prisoners that want to work, so we don't need to be forcing people, but I also understand how people could just consider it a part of the punishment too. I mean, you take away so many rights of a person when you imprison them. What makes this facet special? Is it because we used the magic word slavery and so people suddenly feel guilty because of America's past?
The prisons themselves litreally didn't care enough to even argue against it, which should tell you how little this actually impacts their workforce. My understanding was that people were just getting upset at having to do wildfire related work when things started getting dangerous after they reaped all the rewards and training for that job.
It's like being a firefighter for the pay, chili, and comradery, then balking when you are told to go fight a fire. Your average person could do that and probably be fired on the spot. Prisoners don't get to make that decision.
You understand they weren't paid for that training or job, right?
You understand they weren't allowed to do that job when they were out of prison, right? Even as a volunteer they'd be disqualified. They received no benefits for risking their lives, but we're punished if they did not. They were not sentenced to death.
To your main point, slavery is bad in all contexts. Corporations shouldn't get to have slaves because they pay their workers so badly they turned to crime.
