That's basically what legal incompetence is for SSI. If you have not had money/managed money in the past no one is going to give you money to "practice" with? They aren't in the business of educating one to budget money, they are trying to help one get food, shelter and clothing and that's it. If one has mis-managed (bought drugs instead of food) or not worked/had money to manage before, probably whoever has been managing or giving to/supporting one in the past will continue to be doing that.
