Alexa,

Numbers are not reported by individual countries only but also by individual Consulates/Embassies in various countries directly to the UN.

I am certain that no one is brainless enough to abuse their helpers in front of "outsiders".

Do you know if your friends gave their helpers a day off and let them roam free once a week as they please? Did they let them work 8 hours per day only? Where they compensated for "overtime"? Did they feed them properly or did they let them eat the kids leftovers? Do they give them their salary on time or do they delay it by a week or 10 days or two months? How many husbands tried to sexually harass the helper when nobody was at home? Did the helpers have proper accommodation or is a shoddy room the size of a bed if they get that previlege?
This is not to mention the verbal abuse they have to endure if they dare to make a mistake or brake a household item. How frequently did they allow them to call family and friends at their expense?

Just wanting to have a helper 24/7 when you don't have a physical disability is by itself decadent behavior, letting the helper raise the kids and not caring for your own kids when you know that they are absorbing the cultural/moral/social values of the helper speaks loudly enough about the so called middle class people who employ them.
