tractor, i don't know, really, but it seems that your over all assets, 10.7T general assets, for 181M country, seems kinda low, i've got a 23M country with half that
you might want to check your order strategies under trade,
also, as i'm checking you've got 128B in liquid cash, thats not enough for such a large country, you need to keep around 3-5T minimum.
Materials Purchased -2,700,202.07M SC$
Materials sold or used by Government 619,280.95M SC$
Spending by the Population 1,024,724.32M SC$
Automatic Cash Transfers -255,000.00M SC$
Manual Cash Transfers 1,990,165.09M SC$
Low Level Worker 15,593 SC$ Income of low level workers 15,000 SC$
given that your corporate salaries and government salaries appear to about even, that would tell me that 1T difference in country spending and gov/pop spending is manual purchasing, along with 2T in offensive spending, looks like your basically spending cash as fast as you can get it. thats why your getting the messages about low funds, and over spending.
if you're making manual purchases, that will count against your avaible spending limit for the automatic purchasing under trade strategies, "order strategy and quality," so if you purchase max services, it will take a couple months for the spending limit to replenish, so you can buy other stuff. so instead, try always leaving like 100B spending available for country supplies.
