As far as we are concerned, first, it would be unacceptable to have to pay more for a service because you have functional limitations. It is a recognized principle that a limitation should mean you pay as little as possible.
Second, the vast majority of people we represent live below the poverty line, and, to be able to obtain tax credits, first, you unfortunately have to pay taxes. In our view, the concept of a non-refundable tax credit, as opposed to a refundable tax credit, presents a number of stumbling blocks. Other arrangements may be proposed than overbilling people for a service because they share a particular characteristic. That is unacceptable in our world.
