That doesn't actually mean anything, especially after I've seen how much you have abused definition of "exploit". Literally anything less than an impossible 100% profit pass-through is "exploitation". While operating under utterly-stupid economic assumptions about fixed universal values to add insult to injury.
Is that true? Or do Americans really like having servants?
It appears to be true based on restaurants being one of the worst industries for wage theft. Also tipping enables restaurants to give the impression that good earnings are possible without actually having the wherewithal to provide good wages, meanwhile not taking responsibility for workers.
Completely agree that wage theft is terrible, and tipping is silly. But it seems hard to deny that people love servants when they love their DoorDash, lawn services, and maids so much.
Considering slavery is still legal as per the 13th amendment, yes. We are addicted to cheap/free labor for businesses.
