Quote from Tsing Tao:
If you have russian citizenship, then why the hell are you making me explain the black and white salaries or the tax structure to you? You just want to waste my time, durok?
if i was дурак, i wouldn't be here with dual citizenship,making money in the toughest field 
once again-white\black income works in US just fine. just like in Russia
btw-good luck with immigration to Russia(or any western Europe country) without knowing the language. good luck learning the russian language too(hint-it's extremely complicated..faaar more complicated than english).
