I guess it raises the question - in the instance of say FDW (Foreign domestic workers, who live with a number of families in Singapore) - just because it’s legal, does it make it right?

I don’t know.

Majority of maids live in 1.5m x 1.7m rooms, get paid ~450USD a month (anecdotal guess), are female and see their own kids for maybe two weeks a year, work 6 if not 7 days a week.

Is that a society we should aspire to?
