It depends, my father is disabled and just wanted to feel useful. In the end he was unable to be productive enough for it to be worth the extra time from the colleagues supporting him.

I’d be happy for the government to subsidize the salaries to match an actual minimum wage, but it is unrealistic to expect disabled people to match the efficiency of abled people and compete with them for jobs of an equal salary. They might not be able to find employment very easily then, which really hurts those who wish to participate in society.
