This is not going to happen prior to the coming financial implosion, but it needs to be at the top of the agenda in the weeks following.
The budget process is designed to create excess debt in order to support excess wealth, as it puts together enormous spending bills, that the president can only pass, or veto. Budgeting is to list priorities and spend according to ability. If the government wants to budget, these bills could be broken into their line items and have every legislator assign a percentage value to each one. Then reassemble the bill by preference and have the president draw the line at what is to be funded. As Truman might have put it, "The buck stops here."
