Slavery is essentially still legal in many parts of South East Asia, domestic servants may serve for life becoming almost a part of a family while being paid next to nothing and denied the opportunity to live their own life. This is especially common in the Philippines.
There’s probably some kind of argument about whether such a life is better than starvation and poverty while such conditions remain rampant in those countries… but these people are never given a fair choice - and by fair I mean fully informed and lacking coercion.
