ABSOLUTELY!! Not only should the justifications be available, line by line as well as generally, but also the assumptions and data upon which those justifications are based. Automatic rollovers plus inflation has long been used to bloat budgets. Non-data driven political assumptions also bloat the budget. Budgets are a statement of values. If we are to trust our government to act in our best interest as a nation, and not just for a privileged few, providing the data needed that underlies and drives the justifications for recommended expenditures would be readily available in a standardized format.
