Of course some/most do do it, but first of all, lets look at the typical Bulgarian out-goings, i.e. mortgage or lack of one, rates, electricity etc. I am surprised that none of my Bulgarian workers look emancipated in anyway whatsoever, but I never see them with any food from a shop other than bread. Plus of course, you must have a mobile telephone with endless hours of free calls.
I'd find it difficult to feed the two of us, 3 dogs and a cat on that amount of money, but I am SURE that a lot can and do.
