The only assumption that is missing is how much is a years worth od disability vs a years worth of BI. The reason I ask is that there is defintiely a population of unknown sized that is on disability that maybe should not be on it (NPR/Planet Money covered this)
without knowing how many would switch from disability to BI and/or BJ - hard to say (I would say based on the disabilities described, like severe back pain so no more construction, more would be inclined to switch to BI and not BJ)
