There is no such thing as exploitation or "bending over backwards" being right. Crap is crap. If you decide to stay at the school for a very long time (that being more than a few months) then it goes to show that not only do you know nothing about the culture you are in as you're too busy working and not thinking about what other people around you may believe in, but you also weren't properly educated in the developed country in which you are from. You should've been educated on the values of freedom, truth, etc. that are present in developed countries. However you apparently weren't inclined to understand this properly so you just blindly see anything that happens to you in a foreign country as coming from "culture" which in your mind is something good. Go back to school.
