This article discusses the necessity of the change of current user fee's charging systems regarding
personal assistance services for disabled people. The current system charges user fees on the basis of the
roughly classified income levels, without the consideration of capacity of people's disposable income. Thus,
the irrationality occurs like people with lower income pay more fees relatively than people with higher
income.
To overcome this problem, this article suggests a new model in which user fees should be charged on
the basis of the disposable income with reflecting paying capacities of people compared to those of people
with the highest income.
The comparison between the current model and the new one about the amount of user fee shows that,
under the current system, the majority of people with lower income expenses the fee above their paying
capacities for personal assistance service. This result says that the current system needs to be changed to
the system considering their paying capacity based on disposable income.
