Vodpop,

The way you phrased "they restrict you to some sort of income limitation" makes it sound like you think SSDI is trying to keep you from working. They want you to work. They don't want to pay you money that is for the totally disabled if you can work. The income limits are in place because they figure if you can work enough to make more than $900 a month, then you can work. SSDI wants to encourage people to try to go back to work if there is an improvement in their medical condition, so it allows for the ticket to work, so someone can work part time to see if they can manage going back to work.
