To add on,
When I grew up, we also had several tharu girls working in our house. But my Mom i guess was smarter than all these politicians and big shot people(maharajas). What she did(which i understand now) was went to all the rural areas in terai and brought 2-3 young tharu girls that had become burden to their family (as we all know how family in rural areas treat a new born baby when its a boy{asset} and when its gal{debt}) and bring them back to kathmandu with her. Then she sent about 300-500 Rs to their parents home every 2 months. Now while those tharu girls are helping my mom get her work done, the girls gets free meals(good & healthy food), free housing(sleep in a cozy bed right next to my Mom's bed) and the biggest thing is FREE SCHOOL( bal mandir or Nandi Ratri or Tangal school- cheap schools but its a school where you atleast have a chance to learn and become educated).
I can still remeber two of them got married when they became 19 and my mom paid them for the marriage thinking we(my family) have offsetted their hardwork.
I feel what she did was ten or thousand times better than how they are being treated right now...
