Olympics and Paralympics, activities with disabilities

I do not understand why Olympians with disabilities are paid less than ordinary Olympians ???? At them that needs in a life are less or at them gold - not gold ....... ??????
The whole world is fighting for the equality of people with limited opportunities, creating the most favorable conditions for access of people with disabilities to all the benefits of mankind. A lot of pathos, but in some specific points proves the opposite. I advocate the same fees to athletes regardless of their physical condition.
