Dr. Frank Walsh:

I have thought about how one would go about it. We have limited research capacity and do the best we can. Something like that would involve doing a survey, gathering data and so on. We would not have the resources to do that. There is much evidence from different surveys that ask questions about disability, but once one narrows that down to people on the minimum wage in that survey, the number would be tiny. One just has to go out and get the data, which would be a difficulty for us.
