When politicians talk about ‘running government like a business’ few understand the real world implications for switching from cash accounting to accrual accounting. Money cannot change hands without activity, and unless you lapse approvals eventually, you could end up with imaginary surpluses during the years you had hoped to spend the money and not predicted deficits when the money is actually spent by an activity.
It doesn’t help that municipalities are particularly bad at spending money on infrastructure. 2 years of stimulus funds intended by senior governments typically turn into 5 years of projects at the municipalities, with a bunch of the allocation lapsing due to failure to spend.
