I live in Siberia and I want to say you can make a good money here. While average wage of the teachers is $400-500 per month, you can get much more, but if you work for yourself of course. Goverment don't give a shit for education no matter how good you are. Once a teacher came to us from Australia. He takes $9 per hour from a person and works in group with 10 persons. So, 9*10 = $90 per hour! He can work only one hour per day and 20 days in a month and still gets more than most people 90*20 = $1800/month. Works only for English teachers of course, you can be Nobel prize winner in physics but you cannot make money as much as an English teacher, they are in a great demand especially in the small towns with less 100K inhabitants.
