Private clinics are full of doctors and nurses, who take in principle only duty - at night, on weekends, on holidays. and bla bla bla.

Everything would be like that, but private clinics are full where there are full of payable patients. In the poor depressed region - 1-2 private clinics for the wealthy, and the rest are running in the rows for the reception of OMS and do not binge, because there is no money. For the same reason in the province it is very difficult to earn a nurse, nurse, tutor, housewife - there may be a need for services, but there is no money for potential clients.
