Here in Australia we no longer use the term "mentally handicapped". We are all of us people- some of us have disabilities, some have intellectual disablities from birth, others aquire them later. They are then PEOPLE with -----whatever---disabilities. That describes who they are. They may also be "handicapped" further by the way their society treats them, both emotionally and physically, so that they are unable to achieve to their possible potential, but there is no such thing as "the mentally handicapped". Handicaps are imposed on people with disabilities by people without disabilities.

You still haven't explained your use of the term "poverty minded" as it applies to people with an intellectual disability. I will be very interested indeed to see the argument.
