$200 USD per month? That's just fun money. Are prices that much lower in Ukraine? I don't think they are much lower in Russia because we were looking at ads for houses with indoor pools and the prices were about the same in the US and Moscow. People need a lot more than $200 to live on.
Pensions in Russia are just a bit higher. $270 they say, but the spread is huge as always. Most people I know get the same $200.
