They're forms of slavery.
en.wikipedia.org
The vast majority of "modern slavery" is basically extra-legal indentured servitude, note. Almost anyone who has "experienced" slavery and is alive today did so as an indentured labourer of some kind rather than a chattel slave (certainly in the West).
Ok, but just to clear - they
are forms of slavery.
What they're definitely not is chattel slavery. Almost everything you're saying seems to refer to chattel slavery. Please do read the Wikipedia article.
I'm sorry if I've been imprecise earlier, but they when someone says "milquetoast slavery" to me, they mean indentured servitude or serfdom.
I think you can avoid the word slavery when discussing them, which is the main asset. In Spire: The City Must Fall for example, all the PCs have undergone Durances, which are fixed-term indentured servitude.
I mean, is that not okay? That seems reasonable. It's hard to see how else you would handle the 20th century in a game set in the US. I would generally like a reminder that playing racism up will typically make the game worse for everyone and may take you to bad places, but ultimately it's going to be up to the group.
I mean, it's not like PoC-written Lovecraft-inspired material doesn't engage with racism and so on.
LOL WTH. Jesus Deadlands. I hope to god you're quoting from a like 2000s-era version and they've updated it since. I had no idea.
Sounds like it would make me pretty mad because I loathe Victorian elites with a fire like the sun.
I'm British so I'm less interested in US-set 1800s stuff by and large, and Britain (with the aid of various other Western powers) was in the process of screwing up more or less the entire planet in the 1800s. I don't think any game really addresses the level to which I would want to smash imperialists, that I've seen. This is my main problem with the 1800s - I am incapable of playing a character in them who isn't going to be A Problem and I know it. Which would be fine if the subject of the game was "smash oppression and imperialism", but I am not aware of a single solitary 1800s-set game where that is the goal.
There is a PoC-written Cthulhu RPG or CoC supplement (I can't remember which - it's 3PP if the latter) which I've been looking for for a while, I think loosely inspired by Lovecraft's Red Hook stuff but a Black take on what was actually happening. It looked really cool unfortunately I can't remember the name and searching is failing me. That's 1920s not 1800s though, IIRC.
