I totally understand that the government feels bloated and we could cut costs in plenty of areas, but I think it's way more effective to apoint people into leadership positions that can take a real deep look at things and actually cut what makes sense. Any sort of rapid deep cuts is only going to harm us as a society and likely not actually save that much money. No matter how much money you saved, when you spin up something new that is basically starting from scratch, you're going to spend way more then just fixing what exists.
I think it's the classic coder's dilemma, The code's shit, do I refactor it in place or do I replace it from scratch. Any small or even medium sized project, replacing it from scratch could be the right thing to do, but when you get into large projects, replacing it is just not the right decision if you're trying to save money.
IMHO, refactor the government, don't replace.
