There are certainly challenges to becoming self-employed for people with disabilities; however, there is a certain flexibility that self-employment can allow that in many cases regular employment does not allow. There is flexibility around the number of work hours, the time of work hours, and those sorts of things.
People with disabilities quite often require good direction in helping them look at their business ideas, not just from the perspective of the market--as anyone who is going to become self-employed or start a business would need to do--but at what the accommodations and business challenges will realistically be relative to their disabilities. There are opportunities for people with disabilities to become self-employed, but they have to be looked at in a very realistic and business sense.
I wouldn't say that it's easier for a person with disabilities to become self-employed. In some cases there are significant challenges, but at the same time, because of flexibility and the possibility of working within their own milieu and within a very specific marketplace, the opportunities exist.
I'm not sure if that covers it.
