I didn’t really get this point in the essay. What’s wrong with wanting servants as long as it’s done ethically etc and is not indentured servitude?
The whole gig/services economy is just building this up piece-by-piece: you can now pick the set of household needs you want taken care of for varying levels of money; and practically everyone participates in one form or another. This is exactly a disaggregated 21st century version of servants: paying for convenience. Of course with many issues in implementation, but I don’t see the ethical/moral issue with wanting this kind of thing?
There’s a difference between servitude and slavery. Servitude is voluntary, slavery is not. There’s a gradation between them, and indentured servitude is somewhere in between the two. The “issues in implementation” are exactly where the ethical and moral issue lie.
