Chargeable and free of charge of services have influenced income distribution. A charge for services has been noticed to heighten the use of services. The effect is more profound and ideological than one assumes at first sight. Service producers have to think very carefully about the effects of this. At the same time the user could place more consideration on his/her need for that service if it is chargeable, even if it is only a nominal charge.(Meklin 2002: 29–30; 66–69.)
