I think the technical term is "patronage". I am not very clear on the details. It is just, the bigger the budget, the more people you need on board pulling for it vs. every other project after the same money. Some people will support you because they agree with your priorities. Others need persuasion. You don't personally have the means for persuasion, but the project does, so it comes from that budget. Of course, the more persuasion you need, the more it costs, and the more backing you need. So it is usually better to budget less and plan on overruns, instead. And, finishing on time would mean cutting off all those backers; thus, the schedule is overrun, too. Thing is, most things somebody wants to spend $billions in public money on shouldn't proceed.
