I am sorry to say so, but I am affraid its a bit to late to start with some education. If your parents let your brother to stay home without contributing to the running cost of the household and did not push him to take care of himself he might become unable to do so. Makeing him now to become independent may lead to harms and create very unpleasant atmosphere which sooner or later could lead to more serious problems. Parental love sometimes has very unwanted consequences...
