Also it's just so much easier to get the benefits of constraint without the downsides if one is in charge of the decisions. Like if you can do something with $10k and have $30k to work with, many adults manage to constrain themselves by merely moving $20k to a savings account, and those who lack the requisite executive function for this simple "out of sight out of mind" organizational schema can often function with slightly stronger artificial constraints, sometimes aided by a collaborator. People do NaNoWriMo or whatever, and while many fail, the benefit of the artificial time constraint motivates a lot of people, despite being self-imposed. In either case, this informal method of constraint is more responsive to situational changes or emergencies than an optimization valve that always wants to bring costs down and doesn't understand any of the functional constraints, as is the case for most finance and management arms of "efficiency"-driven orgs. The game theory of budget inflation is really obvious when you consider it in terms of locus of agency
