In observing and speaking with differently abled people and their families, some do not feel safe out in the community or having their family member left to fend for themselves in an environment that doesn't understand their needs. The choice should be theirs and theirs alone to make. Wage differentiation allows them to have work they otherwise wouldn't get hired for and have a level of self worth to earn and spend their own income, in a SAFE environment. If they then feel safe on their own they can then apply for work outside the program and make more money. It's no different than students who do internships for experience and less money.
