Yup. Same reason many great bands don't tour America. Difference is in places like America we tend to have money, but with no interest in good music, whereas in places like Serbia, South America etc the interest is generally there, but without the financial backing.
Back in the day things were structured so most good bands could hit the road hard taking losses and eventually recoup the money (most of the financials handled through the label), but today it just doesn't happen. You can pay to tour all you want but it will end up with you nowhere most of the time.
