I have a strong sense that online work - on CrowdFlower, Mechanical Turk, or Elance - could be the path forward for someone like Jaime. Please do note: I work for CrowdFlower. The beauty of online work is its promise of operating as a meritocracy. Access to the labor market is not about who you know, or how you appear, but about your ability to perform. Everything about Jaime, from his diligence to his incredible cat…
Online work solves the problem of not having something to do, but in some sense, going on YouTube also solves that problem. In my opinion, the value of work for someone like Jaime mostly revolves around the perception of independence (I can take the bus by myself) and the social interactions (having co-workers), and online work doesn't fulfill these as well.

Researching what someone with Down syndrome did 50 or 100 years ago might also be useful. Quite a few manual labour jobs have disappeared through automation. Looking at those jobs disappearing might also inspire.
Looking at places where hand made/artsianal products or services command a premium might also help.
Or why not set up a small business tailor made to him and the things he can do? Balancing between his autonomy as a person and maximising his economic output will always be a challenge, but I could see it being worth the effort.

This scenario of "his own business" is not without a precedent. I don't have any online references, but I remember a colleague telling me about a local business like that, a woodworking shop. It was owned by a very small trust set up by the parents. The person with the mental disability loved anything to do with wood. He was hired, together with a trusted and skilled local worker a generation younger than the parents. This man slowly built a significant partial ownership stake that tied him to the business. The firm was well known and respected in and around the village where it worked.
