I think keeping the family intact is the best way to move forward in life. Living with wife, kids, relatives will makes a person's life enjoyable.

That's why some of the employer's giving opportunity to work husband and wife together.

In this case they need to allow to have their kids as well.

Over all, if an employer wants to hire a maid, He needs to recruit an entire family.

I hope this makes sense, in a way the employer is protected from the life in the earth and the life hereafter.
