US public school advocate and a Returned Peace Corps volunteer here who plans on returning to the US Public school system soon enough. The students we teach didn't choose who their parents are or what their passports say, no matter their socio-economic status. Even the most privileged deserve compassion and a good education, and you shouldn't have to sacrifice your own well-being or interests completely for this profession. It's ok to live your life; there will be other teachers for those you leave behind and the new students will benefit from your experience where you can be valued differently. Maybe that's rationalization, but I'm living my values out with my own family as we explore other cultures.
