...So are we talking about the average in Sofia or Bulgaria, as we know Sofia is not Bulgaria, so we can not make that kind of compartment (for the people that suggested to increase the average amount of monthly income)
My personal opinion is that is almost the same if we take a 25 year old person in the States and same in Bulgaria.
The person in the States earns more money, but also have more expenses, and the person in Bulgaria earns less, but in 95% of the cases don't have to pay for rent, and usually lives with his/hers parents, so basically not paying for utilities or food as well, so the largest % of his/hers income goes for clothes, going out and transportation.
