Commercially thinking providers might thus be tempted to reconsider the supply of unprofitable services. The great importance of the utility service for consumers and the consequent desirability for everybody to actually buy the service make it necessary for the service to be affordable for all consumers. For a number of utility services, passing on the full costs would lead to such high tariffs that the sales of the facility would remain below critical levels. This is a reason to support the facility financially from public funds, which makes it possible to charge consumers a lower tariff and brings the facility within the budget of more people (this is called marit good nature of the utility service).
