As an aside, I’ve seen this happen elsewhere as well. Classic play for wage theft. When I was working as a bartender in London to make ends meet, I had a coworker from Mexico on an expired visa. Great guy and the most hardworking. Well won’t you guess it, guy got picked up by immigration authority on payday.
Indentured servitude has a specific definition to mean working without pay under a contract.
Don’t get me wrong, this is still slavery, but we are all literal slaves to our wages in a capitalist system.
What this post is describing can better be defined as terrorism, which is the use of or threat of violence for a political or religious reason.
Since it’s a combination, maybe we can come up with a new term for it, like “slave terrorism” or something.
