Brit, agreed that change in attitude and mentality is needed but I wouldn't agree with abuse goes on everywhere. Isolated cases of abuse happen all over the world. For you to say "Abuse of maids servants goes on in many countries including Nepal itself"...can you give me a link where there was physical abuse of maid there. Actually, in Nepal there would be few to be counted in hand who can afford to have a maid.
Still I can't deny there may be few unreported cases but that doesn't suffice to say maids are abused there too.
