Health-care workers from countries like Ghana have a difficult time surviving on their pay, since funding for health care is based on the "cash and carry" system. In other words, hospitals earn only what these countries' very poor citizens can pay, leaving little money for the nurses those hospitals need. Able to make middle-class livings in Europe and the United States, many of these health-care workers make the difficult decision to work abroad in order to get ahead financially, leaving their home countries with a shortage of health-care professionals.
