In Russia the chairmen are interested in kickbacks which they won't get with OSS.

Also, it seems that the situation with education in general is still better that in Brazil at least in some regards. In 2014 I worked in São Paulo and had a difficult time communicating with a taxi driver. I was trying to ask him to at least write the amount of money we have to pay for the ride on a slip of paper. Later a colleague explained that illiterate drivers are quite common.

In general Brazil felt mostly like home to me. Maybe Brazil is a version of Russia where homeless people don't freeze to death in the winter :)
