What you say would have more merit if there was free choice for these Bangladeshi people to come and go. Why have their passports been confiscated? Why is there not a viable means (steerage in low cost cargo ships) for them to return home if they wish? The arrangement as it stands amounts to what is called 'Indentured Servitute' which is a fancy name for slavery.
Extra points, though, for trying to turn the issue into something 'dirty and sexual' by using the term fetishise. Tell your masters to give you an extra bonus for your effort, because you've written some excellent propaganda.
